THE BRONX - Students at Lehman College rallied tonight in support of Trayvon Martin, the black Florida teen who was fatally shot by a neighborhood watchman last month.The students wore hoodies at the rally, just as Martin did the night he was killed. The 17-year-old boy was walking back to a relative's home after picking up snacks at 7-Eleven when he was fatally shot by George Zimmerman, police say. Zimmerman says he acted out of self-defense and has not been charged in Martin's death.
