I think the state went way overboard with the charges and because of that, Zimmerman might walk.
Such a shame that a dude can arm himself, stalk a kid, provoke a fight and kill him when he loses said fight, and because of shitty, shoddy police work, will likely get away with it. At least criminally. His life is already ruined either way and I would expect the TM family to win a civil suit down the line.
