I agree with most of your post, and especially the bolded part. I think you're right that if Martin attacked him first then Zimmerman is entitled to claim self defense. However, the eye witness only saw that Martin was winning the fight. As far as I know, he did not see who started it. It's certainly possible that Zimmerman started something he couldn't finish.
I think this comes down to Zimmerman's credibility, which is best assessed by a jury of his peers that actually gets to hear what he has to say.
And even if Martin struck first I still think the attacks on his character are completely gratuitous. A lot of people in that situation would strike first.
Really? You would just up and coldcock somebody because they were watching you? Maybe you need an anger management class or something.
Well, if a lot of people in that situation would strike first, then a lot of people deserve to get shot. End of story.
You can’t deliver an unprovoked beating on somebody who has been following you just because you don’t like the looks of them.
Well, I guess you can, but if you end up shot then you get what you deserve.
“And even if Martin struck first I still think the attacks on his character are completely gratuitous. A lot of people in that situation would strike first.”
That is because you foolishly think this is about Martin and justice. This is as I said in another post about ginning up the base and keeping political power. The people doing this are merely using Martin. They care not a whit about him. In that battle, who Martin really is matters. They are implying he was this nice kid attack by an evil white guy. So the truth about who Martin is matters in this public discourse.
Now if we end up on a jury together deciding this case, nothing about either Martin’s or Zimmerman’s past matters. All that matters is the evidence. But we are not in that courtroom now. The political theatre is important too.
