"A child.". Now who's being absurd.
Zimmerman had every right to keep an eye on a stranger walking around his neighborhood. If I was walking around that way I'd expect someone to ask what I was doing there. Unlike Martin though, I would have had a reasonable conversation; I wouldn't have gone wilding like Martin obviously did.
Martin tried to be a bully, figured he'd beat someone up. He didn't figure that guy was capable of defending himself.
Martin was 17.
child
/CHīld/
Noun
A young human being below the age of full physical development or below the legal age of majority.
Walking around what way? Was he doing the John Cleese silly walk or something? He was walking. That's all.
If somebody asked me what I was doing in such a situation I would tell them "minding my own business." And then I would ask who want to know. Zimmerman had no business harassing him.
There is no proof that Martin went "wilding." You are imagining things that you don't know and can't know.
Supposedly, Zimmerman was not capable of defending himself. Not with commensurate force, anyway.
