University of Texas at Arlington students, members of the NAACP and Arlington residents marched, chanted and rallied in support of the family of a slain Florida teenager and called for the arrest of the shooter.
Trayvon Martin, 17, was shot Feb. 26 by George Zimmerman, who was patrolling the neighborhood where his father's fiance lived. Zimmerman said he shot Martin in self-defense and has not been arrested.
Roughly 200 demonstrators chanted "justice for Trayvon," carried signs reading "no justice, no peace" and wore hoodies.
"This injustice is not OK," said David Butler Jr., a member of the UT-Arlington chapter of the NAACP.
Marchers also chanted "Arrest George Zimmerman, arrest George Zimmerman," as they weaved their way through campus.
The demonstrators said they were targeting stereotypes that many say cost Martin his life.
"Most African-Americans -- young black males in particular -- most of us are good kids from good households, whose parents go to church every weekend, who are trying to go to college and advance our lives," said Jason Shelton, a UTA sociology professor.
People of all races participated in the march.
"I want to see black people, white people, Asian people," Butler said. "What affects one directly affects all indirectly. It's not just a black problem; in the end, it's a human problem, and we need to come together."
Those who marched Monday said that just because the demonstration was over, it didn't mean their voices would not be heard tomorrow.
"Don't let it stop tomorrow," one person yelled during the march. "Let the sound of your feet in this march continue."
"I hope this is more than just a movement," Shelton said. "This is not just a flash in the pan. But the reality is, we have to change people's hearts and minds."
