I don’t necessarily believe Zimmerman did anything illegal, but it was pure stupidity getting out the car and pursuing. It made a bad situation much worse. I agree with your assessment of how this should be handled and its a shame is such a political issue now.
I tend to agree. As a neighborhood watch member, he should have observed, not escalated. An equally poor decision on the part of the youth further escalated the situation, it would seem.
If it comes out in any way that Zimmerman initiated the assault, then I would think that he's in a world of legal trouble. But I haven't seen any evidence to support that theory as yet.
