walking while black - Trayvon Martin

2.) "He didn't identify himself." So what? If he did, was Trayvon obligated to immediately stop running and become compliant?

Not “obligated to” but “might have done”.

I think the point is T had no fucking clue who Z was or why he was following him.

For all T knew Z could have been a homicidal racist, serial killer or sex offender. If Z had identified himself to T as working for the local neighbourhood watch and there had been a number of burglaries in the area it “might” have diffused the situation. T would have realised Z wasn't a cop cops identify themselves but he must have been thinking “who the fuck is this guy and why is he following me?”
