If you're right, we are rid of two bad guys.
The guy who got shot learned a widely understood lesson too late;
Don't pick a fight with old guys, they're to old, too tired to fight, they'll just shoot you.
I think you are confused about who picked the fight in the first place.
I wonder how many people the old bastard shot while he was a cop? (and got away with it) I’ll bet he won’t get away with it this time. He wouldn’t if I was on the jury.
I saw an old guy go completely berserk in a movie theatre when someones phone rang once. The nutcase was in the front of the theatre, the phone ring came from the back of the theatre and I was in between them. I got up and moved. The phone rang one more time and the nutcase started climbing over the seats. His wife made him get down. He was so far away from the ring I am surprised he could even hear it. It didn’t bother me and I was closer. Some people are just looking for an excuse to go nuts on someone.
