The Reverend Al Sharpton, the family of Sean Bell, and an all-star cast of civil liberties advocates joined cyclists in Union Square last Friday for one of the more anticipated Critical Mass rides in recent memory. The gathering, which filled up the south end of the park, came three weeks after the Reverend led hundreds of supporters in an attempt to shut down major bridges and tunnels, protesting the acquittal of the officers who shot and killed Bell.

After a roster of speakers addressed topics ranging from parade rules to police violence to gay marriage, Sharpton tied up the disparate strands with a call for mutual support in the face of NYPD misconduct:

After Sharpton's remarks, Sean Bell's father, William Bell, said what must have been on many people's minds: "I really came to see Reverend Al ride that bike." Sharpton didn't disappoint, eschewing a pedicab that had been reserved for him in favor of his own ride. With the way clogged by photographers, Sharpton got off to a halting start before hitting his stride and riding a circuit from 14th Street, down Fifth Avenue to 12th Street, and back up University Place to the square.

Before the event got underway, I had a minute to speak with civil rights attorney Norman Siegel, who has been involved in the Sean Bell case and in the defense of cyclists' rights. I asked Siegel what he saw as the link between the two.

"There's a huge difference between Critical Mass and Sean Bell," he said, "but there is a need for oversight of the NYPD. When the police abuse the civil rights of Sean Bell, and when they abuse the rights of cyclists, there's common ground." He outlined three steps that could serve as unifying goals: having a permanent special prosecutor for police conduct (currently, NYPD lawyers prosecute cops); putting some more teeth in the Civilian Complaint Review Board; and improving the training of police officers.

On this last point, he said: "This job is so stressful, after 10 or 12 years, you could have someone ready to explode... the cop loses it in some situations. In the Sean Bell situation, they could have handled it differently. And it's the same here. With bicyclists, they're hostile, they grab 'em. There has to be better training."

As for the ride itself, the police showed no inclination to start changing their standard approach to Critical Mass. "There were a lot of tickets given for not having lights and not being in bike lanes," said Mark Taylor, an attorney with FreeWheels, the group that organized the rally. "Those aren't real tickets."

The crowd filled up most of the south end of Union Square.
