How is he innocent? Put yourself in his shoes for one moment. You're in an unfamiliar neighborhood, you're just a kid. You're walking home from the store and a strange man starts following you. Perhaps you hear him on the phone reporting your presence to the police. For what? For walking? He continues to stalk you and he's scaring you. And all you've done THAT NIGHT (which is all that's really relevant) is walk home after buying some candy. That's what makes him so innocent.

Interesting, however, that you concentrated on Trayvon and not one other word from my post.
