Yesterday a radio commentator in New York said Trayvon should not have been wearing his hoodie up. Obviously suggesting that if he had not then he would not have been murdered. This is like the rape defense. When a woman is raped she is often accused of "asking for it" because of the clothes she was wearing, the make up etc.
Trayvon was shot because he was black. He had the right to wear a hoodie or no hoodie, up or down. Women have the right to wear the clothes they want and not have to worry that some man will rape them.
The problem is the murderer and the rapist not what clothes people wear or how they wear them.
