Seems like the poor actual victim (especially viewed from their perspective of the same situation) literally has no right to defend themselves. That should be a concern with the interpretation of such policies as described.
Do you think its ok that "victim" threw the first punch? Should that not come into play, thus calling into question the character of the victim?
If you were in this situation, would you have gone home and called the police, or would you have confronted, and attacked the person following you, without regard to if that person is armed or not?
I am not asking this as a legal question. This is a question of common
ense and self preservation.
You'd be a prime candidate to get mugged or get your entire family shot up. When looking from the victim's perspective of the situation, the story line would go something like this:
1. It's dark and raining and some creepy guy is obviously following me. I'm going to speed up (this is validated in the conversation with the girlfriend and GZ's 911 call of the victim starting to run).
2. You've increased your speed and creepy guy who you don't know continues in pursuit of you. Creepy guy is obviously going to attempt to rob me.
3. For those who say run home and call 911, why would you want to show the mugger where you live and expose them to your little brother who's at home alone? If creepy mugger guy is in hot pursuit of you, what good is it going to do you then to call 911, when dude is obviously seconds away?
4. You need to make a split decision here to keep from being mugged by creepy guy (remember, TM has no idea that GZ is over zealous neighborhood vigilante). You don't want creepy guy following you all the way home and you don't want him to catch up to you from behind and catch you off guard.
In this situation, you are provoked and in fear. One of your logical options is to go on the defensive and attempt to turn the tables on creepy mugger guy by fighting for your life. With that said, no one has a real idea of who threw the first punch (doesn't mean it had to land), what was said, etc. during that physical confrontation except GZ. Everything else is educated guesses and assumptions. All we really know is TM was a better fighter than GZ, causing GZ (in fear of course) shot the victim in self defense of a situation GZ initiated.
With that being said, the flawed part on TM's decision to fight for his life, instead of letting the mugger attack him at home (remember GZ obviously up to no good from the victim's perspective), is that people legally pack heat these days. Back in the old days, GZ would have taken a good whipping, but both would have lived and moved on. These days a lot of crazy people can legally pack heat, shot you for conflicts they generate and legally get away with it, if the victim starts getting the best of them.
