Probably would be in Minnesota, but in Texas, it's probably was not. In Texas, you can use deadly force to protect property, even that of your neighbor, at least under some circumstances, and the facts in this case seem to at least come close to those circumstances.
Once again, it appears that the shooter ignored advice from the cops after calling 911 and did it all wrong. On tape. It appears that the shooter pushed the situation while observing a crime. It appears (I know....)that the shooter stepped out of his house (and safety) and confronted the BG’s on his neighbor’s property. On tape.
I wish him nothing but the best, but this is going to be a tough one to defend.
Just sayin’.....
