Inside the UC protests

1

Hundreds of students showed up at the Mission Bay campus Nov. 17 to protest the eight percent tuition hike that UC Regents are expected to approve on Thursday, Nov.18.


The protests turned violent after police tried to prevent students – and members of the public – from attending a public meeting on the finances of a public university.


The latest hike would amount to a cumulative tuition increase of 40 percent this year alone, bringing the cost of what was once a free public education, and as recently as 1995 was just $1,300 a year, to more than $10,000 — pushing a lot of students out.


Nathan Brostom, vice president of UC business operations, told the Regents that although the university’s balance sheet looks good, its liabilities are growing. Future increases are a possibility, he said, in light of a state budget that leaves less and less for public education.


Of course, UC is also lot of money on campus expansion.


The students made it clear where they stand on this issue: they refuse to believe that tuition hikes are the only way. And there’s a strong case to be made that the university has other options; Bob Meister, a professor of political and social thought at UC Santa Cruz and president of the Council of UC Faculty Organizations, released a detailed letter to the Regents explaining several options for avoiding the increase. He spoke to the board during the public comment part of the meeting.

At a press conference during the event, UCSF Police Chief Pamela Roskowski noted: “I want to acknowledge that tensions are high.” That was an understatement.


Protests lasted all day, leading to 13 arrests.


The first major police backlash happened when protestors attempted to rush a police barricade, which stood between them and the regents inside the community center. Police lined the barricade’s inner wall and pushed back as the wave of sign-holding students swelled against it.


Roskowski referred to the “angry, unruly, aggressive” protestors and said that they picked up a part of the barricade and used it as a weapon, injuring at least one officer. She also said that protestors tried to pull an officer over the railing and onto their own side. This was when police retaliated with pepper spray — and, by the looks of what was caught on camera, loads of the stuff.


Roskowski defended the use of pepper spray, saying it is the least lethal weapon that officers carry, and that police used it here “in lieu of a baton.” The video shows police spraying protesters with what looks like a hose.


In a separate confrontation, a large group of protestors apparently attempted to enter the community center from a walkway in the adjacent parking garage. Video shows protestors pushing against a wall of police officers, who stood as a human barricade.


In another video, one of the officers breaks away and enters the crowd. He then struggles with protesters momentarily before he regains his footing and stands in the crowd’s center — with his gun drawn and pointed at the crowd.


Roskowski said the officer attempted to fend off the protestors, but that they took his baton from him and struck his head with it, and he pulled out his gun in self-defense.


We’ve looked at the video a number of times, though, and while the scene is chaotic and it’s not always possible to see the officer every moment, and he does lose possession of his baton at one point, there’s no clear visible evidence of any protester taking it from him. And there’s no evidence at all of anyone hitting the helmeted officer with the baton.


In fact, it’s hard to figure out why he charged into the crowd in the first place.


Look for yourself.


The student who allegedly attacked the officer with his own baton has been charged with assault with a deadly weapon. The remainder have been charged with obstructing an officer from the discharge of his/her duties, which is a misdemeanor.


When asked whether there would be an investigation into whether today’s police response was appropriate, Roskowski said “There is always an investigation.”


The police force present at the Regents meeting consisted of 60 UC officers and 35 borrowed from the University of San Francisco.

Rev. Billy exorcises the demon sit-lie measure

17

This afternoon in the Mission District, a crowd gathered to bear witness to an exorcism. Reverend Billy had come from New York City to banish the demon from SF. That demon was Prop L, an unholy measure to ban people from communing on San Francisco’s sidewalks.
“The only fundamentalism is the absence of fundamentalism!” bellowed the Rev. Bill, a former San Francisco performance artist turned pastor of NYC’s Church of Life After Shopping (which was in town to perform tonight (Mon/26) at the Victoria Theater for its Earth-a-llujah, Earth-a-llujah Revival Tour).

Rev. Billy cited constitutional dicta on behalf of civil rights: that we are all, even those without addresses, equal. The good reverend followed with a defense of the unadulterated and often unpredictable daily experience out there on the streets of San Francisco, apt to shape a human in good and thoughtful ways, that would find itself stifled if city regulations seep onto our sidewalks.

Rev. Billy’s choir ended his sidewalk sermon with a song that repeated, “Speaking freely sets us free,” and whose chorus built to:
“Standing up in public space…
Breaking in to public space…
Shouting out in public space!”

Sup. John Avalos spoke after Rev. Billy, and no sooner had he taken the mic than he accused Police Chief George Gascon of suffering a demon of his own: “hubris.” Avalos referred disapprovingly to Gascon’s previous attempts to tackle drugs and Critical Mass, the city’s monthly bicyclist phenomenon.

In reference to Prop L, Avalos shared that when he came to San Francisco, he knew “three people, had $1,000 in my pocket,” but would have been sleeping on the street if not for a friend’s couch and kindness. He called San Francisco a “sanctuary city,” where people can “find a pathway in life to something better, like I did.”

Gabriel Haaland, a Haight neighborhood resident and labor leader, took the mic and proclaimed that “I am, we are, you are, the riff raff! Because the rent is too damn high.” He questioned whether some have taken to the streets partially because of San Francisco’s high cost of living.

SF resident Selina Gomez Sutton said of Prop L: “a San Francisco without street performers and musicians? Crazy.”
But Prop L is also about something other than civil rights, street-side music, and “cleaning up” Haight Street. It’s also about tolerance.

Tellingly, just a few feet away from, and entirely throughout, Rev. Billy’s sermon, a man sat nearby barking and shouting gruffly at apparently nothing but for what (he must have thought) were good reasons indeed. I was there the entire time, and can say that not one attendee told him to stop. Perhaps they were simply jaded to such conduct — or perhaps it was because they respected his right to exist.

Beat patrols: A case study

14

If you want a case study that illustrates why San Francisco needs Proposition M, taken a look at Bernal Heights.

In 2008, two people were killed at the Alemany public housing project, topping off a disturbing increase in street crime. Neighborhood activists responded by working successfully with the captain of the Ingleside Station to a beat cop on Cortland Ave. Crime dropped.

But several weeks ago, Captain Louis Cassanego cut that foot patrol, citing the need to reallocate scarce SFPD manpower to more violent areas.

We couldn’t reach Cassanego, but at an Oct. 6th Police Commission meeting, Chief George Gascon said the beat patrol fell victim to budget problems. He explained that a beat cop on Cortland wasn’t needed anymore because the policy “was set there at a time when there was an increase in robberies… in this community that is no longer there today.”

But comminity activists say that’s precisely the point: “When we got the beat cops, crime went down,” Joseph Smooke, executive director of the Bernal Heights Neighborhood Center, told us. In fact, Smooke said, the foot patrol reduced overall crime in the surrounding neighborhoods as well.

And now, with the foot patrols gone, residents fear that crime will rise again.

Supervisor David Campos, a coauthor of Prop M, told us: “It doesn’t make sense: the community wants more policing, not less. They rightly feel that we’re moving backwards, that something they worked very hard for is being taken away.”

Prop M would hamper future foot patrol cuts by requiring the Chief of Police to prescribe a comprehensive “Foot Beat Patrol Program” for all SFPD stations.

Says community organizer Buck Bagot, who volunteers with the Bernal Height Neighborhood Center, “It’s hard not to think [Prop M] makes sense.”

Prop M could also address what Bagot and Smooke agree is the larger problem: community-police synergy. Besides mandating foot patrols, Prop M would require the Police Commission to “adopt a comprehensive written policy on community policing,” including “a plan for… open communication… among [SFPD] personnel and community members,” with a focus on “neighborhood-specific policing priorities and strategies.”

In recent years Bernal Heights community groups have fallen somewhat out of step with local police. Communication with Ingleside Station has at times been strained. The station’s former captain, David Lazar, started a program in August of 2009 that alloowed merchants and residents to call cell phones that beat cops carried on duty. Cassanego ended that program, too.

Cassanego cut the Cortland Ave beat, he compensated by extending two bike patrol beats into that area. Though Bagot is skeptical that this will be effective, losing personal access to the police irks him most. “At least if we could talk with [the cops], we could work with them…. But if they’re not going to patrol there anymore, and we can’t call them on the cell phones, then we’re kind of floating free.”

Much of the controversy around Proposition 19, which would legalize marijuana in California for even nonmedical uses, involves speculation about what comes next. Hash bars on Market Street? Packs of joints next to the cigarettes in Mission District bodegas? Bags of green buds available with the bongs for sale on Haight Street? They are questions that have yet to get serious consideration in the city where the medical marijuana movement was launched.

The measure would give local governments almost complete control over how to regulate recreational-use cannabis sales in much the same way that cities set their own standards for medical marijuana dispensaries, a realm in which San Francisco has shown real leadership and created a well-functioning, successful, and legitimate industry (see “Marijuana goes mainstream,” Jan. 27).

But San Franciscans have been slow to prepare for the post-Prop. 19 world, with some other Bay Area cities leaving it in the dust on these issues. Oakland City Council Member Rebecca Kaplan, who is now running for mayor, not only spearheaded that city’s ballot measures on taxing recreational pot sales and permitting large scale growing operations, she’s actively talking using the Amsterdam model to revitalize the city’s downtown business district.

“[Hash bars] absolutely potentially would be part of the mix,” Kaplan told us when we asked about the issue during her mayoral endorsement interview, seeing it as part of a multipronged economic development strategy.

When asked if Oakland should have places where people could go to blaze legally, something Oakland doesn’t allow in its medical marijuana dispensaries, Kaplan said, “Yes. Oh yeah, we’re definitely gonna have those. The only question is gonna be whether the consumption facilities are separate from [those for] sales,” or if they’re under the same roof.

Kaplan thinks this will be part of the winning strategy that takes cannabis use off street corners while acknowledging its appeal to visitors and “synergy with the restaurants. When I talk about wanting to replicate the Amsterdam model in Oakland … it doesn’t just mean that you have … a regulated cannabis facility. You also have restaurants, shops, pedestrian safety, nice lighting, patio dining, musicians, artists.”

She points out that although an Oakland-regulated cannabis industry may use current alcohol regulation as a template, the two substances would not be sold alongside each other. “Frankly, ABC [California Department of Alcoholic Beverage Control) will freak out.” That means, at least in Oakland, you won’t be able to purchase cannabis at bars, liquor, or grocery stores.

On this side of the bay, Sup. Ross Mirkarimi — who wrote the regulations on the city’s medical marijuana facilities — says it is “extremely premature” to contemplate Amsterdam-esque hash bars. “That would have to occur within a strong regulatory framework,” he said, one the Board of Supervisors has yet to envision. San Francisco attorney David Owen, who has helped advise some medical marijuana purveyors, said some dispensaries currently allow on-site medication, and San Francisco might legislate to extend the practice to bars.

Meanwhile other California cities such as Berkeley and Oakland are anticipating Prop. 19’s passage much more proactively. Berkeley’s Measure S would tax cannabis businesses, applying different rates to for profit med-use cannabis businesses, nonprofit med-use businesses, and rec-use businesses (which won’t exist unless Prop 19 passes). The measure would secure medical-use cannabis for low-income patients and tighten regulations on Berkeley’s current med-use dispensaries and cultivators regardless of how Prop. 19 fares. There’s also a Measure T on the ballot that would establish a new committee that, in the event that Prop. 19 passes, would advise city officials on how to implement it.

Berkeley City Council Member Kriss Worthington said planning for the post-Prop. 19 world is smart to “synchronize a forward movement on the state and local level” and to “hit the ground running,” a sentiment that Kaplan also voiced for Oakland and one shared by other cities.

Stockton’s Measure I would tax rec-use cannabis businesses at a higher rate than med-use businesses. Sacramento’s Measure C is similar, containing a provision for a rec-use tax range if Prop. 19 passes. Richmond’s Measure V would tax 5 percent of gross sales of cannabis, and could apply to rec-use businesses too. Oakland’s Measure V would add a 5 percent tax to other taxes already on med-use cannabis, and put a 10 percent sales tax on rec-use cannabis. Measure H, on Rancho Cordova’s ballot, would tax personal cultivation at a higher tax on any square footage beyond the 25 square feet that Prop 19 specifies. Long Beach’s Measure B would establish a business license tax on the city’s potential recreational cannabis businesses. Even Albany, which has no dispensaries, would tax for-profit and nonprofit dispensaries differently through its Measure Q.

But Mirkarimi said he would like to tax marijuana cultivation, and has even voiced support for med-use cannabis dispensaries working directly with SF General Hospital to provide to patients, “thereby segregating a special use” and keeping cannabis prices low or nonexistent based on patient needs.

So if Prop. 19 passes, where will San Franciscans be able to purchase rec-use cannabis? Current med-use dispensaries may be a logical choice. “We already have the infrastructure,” said SF dispensary Medithrive co-owner Daniel Bornstein.

Whereas alcohol purveyors are accustomed to providing one barrier to purchase (when they card the buyer), dispensaries such as Medithrive offer many. “We already card and only accept patronage from those with a valid doctor recommendation. We also require he/she become a member of the dispensary and limit to one visit per day.”

When he contemplates whether Medithrive might provide rec-use cannabis in the future, Bornstein says “If [the city adopts] a responsible statute that’s fair, we would welcome the opportunity to offer a broadened service to more people.”

That avenue troubles Mirkarimi. “I don’t know how that works,” he said. Rec-use cannabis purchase would require no doctor’s notes and could occur within a for-profit business model. How would dispensaries legally reconcile making money under their nonprofit status? “I don’t want to put that burden on them,” Mirkarimi said.

Prop. 19 offers other potential implementation conundrums. For example, the measure will only give local governments the option to legalize the limited cultivation/sale of cannabis. Legalization won’t be compulsory. Therefore, it is likely that a post-Prop. 19-approved California will become a patchwork of alternating “dry” and “wet” municipalities.

So let’s say you’re on a road trip and you pass through many cities that all treat cannabis differently. Bornstein and his Medithrive partner Misha Breyburg worry about such a “patchwork of legal complexity.” But Prop. 19 provides for the legal transport of cannabis through cities that prohibit its sale, and California Assemblymember Tom Ammiano has already proposed legislation to smooth out the rough spots in Prop. 19 and answer open questions.

So for now, everyone is just waiting to see what state voters do.

Lynette Sweet’s finances: Curiouser and curiouser

4

By this time it’s old news that Lynette Sweet, current BART Board Budget Committee chair and District 10 supervisorial candidate, has some issues with the Internal Revenue Service. She owed the IRS taxes going back to the year 2000, and the consequent lien on her property exceeded $20,000 in 2007.

Sweet says she never knew about the lien and thought she’d paid the taxes.

We’re still trying to figure out exactly how this happened — and the trail gets more and more convoluted.

We first called Sweet early in September, after we read about her tax troubles in the Chronicle. When we asked Sweet how she could have been unaware that the IRS was after her, Sweet told us that she’d been working with the tax firm JK Harris. She and Harris reached a deal to pay the IRS $14,500. She told us she bought a cashier’s check at Wells Fargo and mailed it in. But for some reason, she made the check out to herself, not the U.S. Treasury — so the IRS couldn’t cash it.

Normally, when you owe the IRS money, they let you know. But in this case, Sweet says she heard nothing from the feds.

When the Guardian pressed her, Sweet blamed JK Harris for not having forwarded her any of the mail in question. “I gave them power of attorney,” she said. “They had all the communications from the IRS.”

But we reached the the tax firm recently, and the folks there beg to differ. Gina Anton, Director of Corporate Communications at JK Harris, told the Guardian that any mail the IRS sent, it sent to Sweet. JK Harris’s role in Sweet’s tax kerfuffle appears modest — she hired the firm to merely act as intermediary between herself and the IRS.

Said Anton: “Our role was to obtain documents from both her and the IRS to determine what amount she could afford and what the IRS would consider an acceptable amount.”

JK Harris did not cut any checks, or inspect any checks after Sweet had cut them, Anton told us. Just the opposite: whatever documents the firm had prepared for Sweet, they sent to her for approval before forwarding them to the IRS.

Furthermore, said Anton, JK Harris was trying to reach Sweet for two years, after Sweet sent the IRS the dubious cashier’s check that she had hoped would diffuse her tax problem. Sweet finally returned JK Harris’s calls when she found out the IRS could not cash the check.

It’s all pretty odd for someone who’s worked in the banking industy for 22 years.

Questions surrounding Sweet’s finances reach beyond troubles with the taxman. She told us recently that she has worked at two companies that she never listed on her economic interest statements.

In her discloure forms, viewable at the BART Board website, she lists no sources of income after 2004, when she reported that she was employed by BayCAT (Bayview Hunters Point Center for Arts and Technology). However, in a very short and heated interview Sept. 10, Sweet told the Guardian that after she had worked at BayCAT, she had also worked at the African American Interest Free Loan Association and Trans Bay Cable.

In fact, she said she had worked at Trans Bay Cable, which is building an electricity line from Pittsburg to San Francisco,  until May of this year, when she left the company to run for office.

Which raises the question: If she was working all those years, why do her economic interest statements show no sources of income at all from 2004-2009?

The Guardian has attempted many times over the past week to contact Sweet to follow up on that question, but she’s stopped returning our calls or responding to our emails. (She’s also refused to come talk to us for an endorsement interview.)

Here are the questions her campaign has decided not to answer:

1.) What were Sweet’s periods of employment with the African American Interest Free Loan Association and Trans Bay Cable? Did she receive any income for this work? Whether yes or no, would she like to comment on the nature of that work?

2) What was the source of the tax that Sweet owed the IRS? Was this a tax on income? If so, then for income from work with which companies?

3) Why did Sweet elect to pay what she owed the IRS by means of a cashier’s check? (Why not a personal check?)

We’re also wondering why she didn’t list any income on her disclosure forms or why she made the check out to herself.

If she gets back to us, we’ll let you know.

 

PG&E’s secret pipeline map

9

news@sfbg.com

>>CLICK HERE TO VIEW THE FULL-SIZE PG&E SECRET PIPELINE MAP (PDF)

It’s been nearly two weeks since the pipeline in San Bruno exploded and killed four people, injuring many more and destroying 37 homes. And it’s left a lot of people in San Francisco wondering: could it happen here?

Of course it could. PG&E has more than 200 miles of major gas pipelines under the city streets that are scheduled to be replaced — and that means they’re reaching the end of their useful life. Just like the pipe that blew up in San Bruno.

Are any running under your home or business? PG&E isn’t going to tell you.

That’s bad. “The public has a right to this information,” City Attorney Dennis Herrera told us. And Sup. Ross Mirkarimi has introduced a resolution calling on PG&E to make the locations of its pipelines, electric lines, and other potentially parts of the company’s infrastructure public.

But here’s what worse: even the city’s public safety departments — the ones that would have to respond to a catastrophic event involving a gas main break — don’t know where those lines are.

“I’m still looking for that map myself,” said Lt. Mindy Talmadge, a spokesperson for the Fire Department.

The city’s Public Utilities Commission, which, among other things, digs its own trenches to install and repair water pipes, doesn’t have the PG&E map. Neither does the the California PUC, which regulates PG&E.

It might also make sense for the City Planning Department to have the map; after all, zoning an area for the future development of dense housing that sits on top of an explosive gas main might be an issue. “People need to start holding PG&E accountable,” Planning Commission member Christina Olague told us. “Why shouldn’t PG&E release [the map] given the recent tragedy?”

PG&E insists that the exact location of the gas mains should remain secret because someone might want to use the information for a terrorist attack. But if the San Francisco Fire Department and Department of Emergency Services can’t get the map of the pipelines, something is very wrong. Even Sup. Sean Elsbernd, who has been allied with PG&E against public power issues, agreed that “the public safety agencies should certainly have that information.”

The Mirkarimi resolution urges PG&E “to cooperate with the city’s request for infrastructure information.” Mayor Gavin Newsom has already appointed the fire chief and city administrator to conduct a utility infrastructure safety review that would evaluate the location, age, and maintenance history of every pipeline underneath city streets.

Not every state allows utilities to keep this information secret. In both Washington and Texas, maps of underground pipelines are easily accessible, said Carl Weimer, executive director of the Bellingham, Washington-based nonprofit Pipeline Safety Trust. Texas even has an online system, he said.

But in California, PG&E keeps even essential safety agencies in the dark. If a fire came near where a PG&E pipeline was buried — or if an earthquake fractured some of the lines and gas started to leak — Talmadge said the San Francisco Fire Department wouldn’t be able to do anything about the explosive gas except call PG&E. Only the private utility can shut off the gas, which is under high pressure in the main lines.

“We radio to our dispatch center and request PG&E to respond … They would contact PG&E and have them respond,” she explained.

The department doesn’t prepare specifically for that sort of event. “We do not have a specific gas leak training … it would be more of a hazardous material training,” Talmadge said.

The remarkable thing is that much of the data the city doesn’t have — and PG&E won’t give up — can be pulled together from publicly accessible data. The major news media, particularly The Bay Citizen, have been pursuing the story and have run pieces of the map. Several newspapers and websites have published rough maps outlining where the major underground pipes are.

But as far as we know, nobody’s done a full-scale look at what the existing public records show.

Using information that the U.S. Department of Transportation has put on the Web, we’ve managed to put together a pretty good approximation of the secret map PG&E doesn’t want you to see.

We took a map from the DOT’s Pipeline and Hazardous Materials Safety Administration and layered it over a map of San Francisco. The maps of the southeast part of the city are more accurate; the information on gas mains going through the north and west side of town are sketchier. But the lines appear to run parallel to major streets, and we’ve put together a guide that at the very least can tell you if there’s a potentially explosive gas line in your neighborhood — and maybe even under your street.

Obviously, every house or business that has natural gas service — and that’s most of San Francisco — is hooked up to a gas pipe, and those feeder pipes run under almost every street. But the gas in those lines is under much lower pressure than the gas in the 30-inch main lines shown on this map, where pressure can reach 200 pounds per square inch. It was a main pipe that blew up under San Bruno.

It’s not surprising that the southeast — traditionally the dumping ground for dangerous and toxic materials — would have the most gas mains, and the most running through residential areas. One line, for example, snakes up Ray Street and jogs over to Delta Street on the edge of McLaren Park and near a playground. It continues under Hamilton and Felton streets, under the Highway 280 and onto Thornton Street before heading into the more industrial areas near Evans Avenue.

Another main line goes under the south side of Bernal Heights, running below Banks Street, around the park, then down Alabama Street to Precita Street, where it connects with 25th Street. That line then heads to Potrero Hill, where it follows Rhode Island Street to 20th Street.
