So you’re saying that Martin had a perfect right to beat the crap out of Zimmerman when Zimmerman was returning to his truck? Get a grip.
I’m saying in the real world you don’t go looking for trouble. When I was young and went to bars, all you had to do was say the wrong thing or look at somebody the wrong way, and you were in a fight. Maybe I’ve missed it, but it appears this kid had a legitimate reason to be in the neighborhood, and was not observed doing anything that indicated criminal intent. Maybe trailing people you don’t know in your neighborhood with a gun was normal for Zimmerman, but it was nonetheless provocative. It was probably inevitable that eventually he’d run into some kid with an attitude and either Zimmerman would be dead or the kid.
