Self defense is fucking bullshit when u initiate the altercation. what was Trayvon supposed to do? Zimmerman is not the police. Secondly, the fact that Zimmerman's "Friends" were allowed to testify, but not Trayvon's parents is appalling and should have been challenged. and any of the overmatched, overcompensated, old as fuck "experts" they hired to testify should have been thrown out, especially since later that retired doctor said that his testimony was wrong.
edit: plus Zimmerman's past could be questioned endlessly as well as his inability to listen to the police dispatcher.
the entire fucking thing was a sham
