I too live in central Florida, and agree it's very rare to see some onme wearing a hoodie, and iirc, it was 60 degrees at the time Martin was shot. It was raining, and I do not believe the hoodie should be blamed at all for Martin's death. Perhaps his action (IMO) of suddenly pulling the hoodie up, at least partially obscuring if not his face, at least is head, when he noticed Zimmerman watching him added to Zimmermans suspicions.
I was a victim of a vioent crime back in October of 1993, attacked, robbed, cornered behind a counter, and cut repeatedly with a razor blade box cutter. Several of the cuts were to my cheek and chin, which bled so much my attacker though he had slit my throat and left.
The attacker was a young black male wearing a baseball cap and a hoodie pulled up over his head.
FYI, my attacker was released from incarceration September of 2011. Crime doesn't pay. There is a WS Mod who can verify this for those who may doubt.
