Cops can't shoot a fleeing suspect unless there is an imminent danger to them or someone else, why should civilians?
Cause they're in TEXAS BABY!!!
THREADJACK:
I have a student who is moving to Texas after the school year is over. He isn't excited about it and was making fun of Texans. In my most paternally concerned voice I let him know that this was a bad policy. If there is one things that Texans love, it's Texas; that is somthing I always liked when I lived there. He is probably 120 soaking wet and the idea of him getting his ass whipped by some big boys from Houston doesn't sit well with me. I dunno, maybe a smart-ass freshman would be well served by a good old fashion ass-whippin. If he is wise he will heed my words, if not, he may become wise the hard way. Worse things could happen than becoming wise the hard way.

And, because if someone steals carnal knowledge from my wife they have earned a meeting with The Almighty Old Testament style. And, because we have a precedent here establishing Old Testament justice for the rapist. The fact that she lied is totally irrelevent to the question. Dude should have considered the fact that a women who would screw around on her husband may not stand up for the guy she is doinking for kicks.
It's like I tell my son about fighting; we are strong to defend those who cannot defend themselves. If we do not fulfill that duty, then we don't deserve the strength we are given.
