A judge has set a trial date for the self-appointed neighborhood watch volunteer who shot and killed unarmed African-American teenager Trayvon Martin. George Zimmerman is charged with second degree murder for the February 26 attack in Sanford, Florida. He appeared in court Wednesday, and his trial date was tentatively set for June 10. But Zimmerman’s defense team has said they will likely request a hearing under Florida’s controversial stand-your-ground law that would allow Zimmerman to make the claim before the trial that he acted in self-defense.
