It seems that you are the one who is confused. In the first post you quoted, I said that the shooter thought the man had raped his wife. In the scond post, I said that it doesn't sit well with me that Texas law allows you to shot someone who is not a direct threat to you at that moment (even if you are under the impression, correct or otherwise, that they are a rapist). Even if he had been a rapist, this guy was running away and not threatening the husband or the wife. Please explain to me where the contradiction that you seem to be accusing me of is? I can understand if you disagree and I would be shocked if you didn't but the 2 statements are in no way contraditory or indicative of any confusion on my part.
I will agree with your statement that you hope I am never faced with this kind of situation, and I hope the same for you and your family. I also hope neither of us ever have unarmed loved one's who get shot in the back because someone mistakenly think they are criminals.
