I get what you're saying and I agree that this is how our system does and should work.
But what I am reading in a few of these posts is that nobody saw TM lay a hand on GZ. So saying that GZ shot TM because he was being beaten isn't a fact, but the defendant's testimony. That isn't any more factual than Jodi Arias claiming self-defense. I mean, yes, it could have happened in GZ's case, but we really don't know. Only GZ says so. KWIM?
What really worries me is how easy it would be to just shoot someone, then give yourself a few superficial cuts and scrapes to support a self-defense claim (Darlie Routier sp?). Luckily, it doesn't always work.
I honestly don't know WHAT to think of this case or what to believe. But I do know if GZ had listened to the police, none of this would have happened. MOO
But this is incorrect, there is evidence, from both witness and forensics, that actually does show that TM was on top of GZ. The logical conclusion is TM is beating GZ because GZ has injuries, no matter how slight.
Someone needs to explain how you give yourself the injuries we're talking about in the timeframes here. He didn't run into a tree or a mailbox, this isn't Looney Tunes.
