Trespassing? yes. Breaking the law? Yes. Deserving of arrest and deportation? Absolutely yes, Deserving of some jail time for his law violation? Yes again.
Deserving of being shot? No.
Making the lame excuse that the shooter thought the man was a hog? Lame, and no excuse at all. Had it been another paying hunter that was shot, or perhaps someones young son or daughter along on a hunt that got shot because someone thought they were a hog would be the same thing. Wrong, and without excuse.
What were the actions that cost the man his life? He wasn't stealing, or attacking the shooter. He was trespassing. Stupid thing to do, and way too many illegals are crossing our borders, but I can't agree that the trespasser is at fault for his death. No excuse to shoot a human and then say, "I thought it was a hog, or a deer", or whatever game animal you can come up with.
Impeach the President because someone in Mexico can file a lawsuit? Thats crazy. Anyone can file a lawsuit. That doesn't mean they can win, or even should win. But this man was shot and killed. He wasn't just roughed up by a landowner. He was shot and killed by a paying "hunter" and then apparently, or atleast allegdly not given immediate medical attention.
