The 911 operator told him to stop following him. It sounds like he didn’t listen. I imagine if somebody started following me through a neighborhood, I would go over and talk to them too.
Now you are out and out lying (or trolling). He said "you don't need to do that." But I'll give you the last word 'cause I'm not going waste any more time on you.
Talk to him? Or start beating the crap out of him...and not relenting when the person is screaming for mercy?
Talk to him? Or start beating the crap out of him? And not relent even as the person is screaming for mercy?
I'm going to offer you a suggestion. Whether you take it or not is up to you.
You have a pre-conceived notion of what happened, and are twisting the narrative to fit it. None of the facts (as they are coming out) support your pre-conceived notion.
Zimmerman -- by his account, by the recordings, and by witnesses -- did not initiate the use of force. Martin did, and it wasn't justifiable under the law. Unless more evidence becomes public that contradicts that, Zimmerman acted in self-defense.
All Martin had to do was tell Zimmerman that he was a guest of his father's girlfriend, and there would have been no escalation to violence. Zimmerman may not have believed him, but that would have been an easy question to solve -- by either walking together to her residence, or calling her.
Barring new and contradictory evidence, the outcome was Martin's responsibility.
