in Florida, if trayvon was 21, he would have been justified in lying prone in the ditch and shooting zimm full of bullets when his ass came around the corner. A big fat man chasing you through the dark for 2 blocks... yes, you sure as @#^*& SHOULD be in fear for your life. You don't have to wait for the fat man to actually shoot you... Ya can cap him first.
Trayvon could have hit him with a brick - out of fear of his life - and that'd been fine too.
Trayvon's mistake here was using fists when he should have been using a deadlier weapon to protect himself against the man violating his consitutional rights in a very scary manner.
Just imagine how pissed any of us would be - if we did ZERO wrong, and some big fat hero wanna be decided to chase us 2 blocks with a gun cause he didn't like our appearance - how pissed and terrified would we be?
