Tell that to the parents of the students murdered in Idaho! What could I possibly think If I find someone in MY HOUSE uninvited other than they are going to hurt or kill me? Being drunk or high is NOT a legitimate excuse! If I find someone other than my wife or kids in my house, I'm assuming he/she is there to cause harm to me or my family! My job is to protect and If that means putting two to the chest and one to the head that's exactly what's going to happen!You have the Right to defend yourself no matter where you are, but just because someone is in your home does not mean they are a threat to you.
As for legitimate self defense cases being targeted for prosecution. Can you list a few so we can see what you're talking about?
