More than one hundred people marched down Crenshaw Boulevard to Leimert Park Sunday afternoon, rallying for justice in the case of Trayvon Martin, the Florida black teenager killed last month by a self-appointed neighborhood watch volunteer. 

“Trayvon didn’t have to die," the crowd chanted. Marchers carried a huge white banner flagged by smaller signs and palm tree leaves. "We all know the reason why. The whole system is guilty."

A dozen representatives from the Black Riders Liberation Party walked near the front of the crowd. Dressed in black jackets, pants and berets and holding their right fists in the air, they chanted “Trayvon Martin, never again! Oscar Grant, never again! Too black, too strong! All power to the people.” 

Cars slowed and honked horns as they passed, a drive-by show of support. Protesters took the chance to hand them flyers detailing the incident. 

Martin, a 17-year-old high school student, was shot and killed by 28-year-old George Zimmerman, who told police he had acted self-defense. 

At the time of the incident, Martin was returning to his father’s fiancee’s house from a convenience store, carrying a bag of Skittles candy and an iced tea. He had no weapons on him. 

Zimmerman has yet to be charged in the case. This shooting has sparked outrage and protests nationwide, prompting calls for justice and opening up the local police department to public scrutiny of their treatment of the case.

The protesters marching nearly a mile and a half south to Leimert Park on Sunday were among those outraged citizens.

“We can never stop as long as George Zimmerman is allowed to walk the streets free,” said Jubilee Shine, one of the organizers. 

He said he and his fellow protesters were also fighting for justice at home in L.A. “There are many instances of people that have been mistreated, abused, killed, beaten by vigilantes, by racists, and by police themselves,” he said. 

Jsané Tyler, a community representative and parent, said Martin’s is not an isolated case, and said it reflected a greater injustice toward the black community.  

“I’ve been that child. I’m part of the generation where we came after our forefathers and thought we would be given a better chance," Tyler said. "In 2012, we are still being gunned down on the street." 

Tyler brought her 11-year-old daughter to the protest to teach her to be “socially conscious” and “civic minded” about issues in the community. 

While speakers at the park stepped up to give voice to their outrage, Lisa Marie Williams stopped passers-by to join the movement in later meetings.

“We need organization first," she said, "and then you strike back."
