AMITYVILLE - About 800 people came together today in Amityville to demand justice for 17-year-old Trayvon Martin, the Florida teen who was shot to death by a neighborhood watchman.

Organizers say the march and rally are meant to shed light on a self-defense law that needs to be revised, and also call for due process in Martin's killing.

According to authorities, on Feb. 26, the 17-year-old boy was walking to his father's house in Sanford, Fla. when he was gunned down by Zimmerman. The 28-year-old has not been arrested after claiming self-defense under the "Stand Your Ground" law.

The Martin case has also spurred conversations about race nationwide. In a recent Christian Monitor Poll, twice as many African-Americans and Hispanics as whites said racial profiling played a role in the teen's death.

"It was Florida this time, but it could be Amityville, Copiague, Wyandanch, West Babylon, North Babylon," says Bishop Andy Lewter, of the Hollywood Full Gospel Baptist Cathedral.
