I agree with you.
I've read where people say he should get a medal.
Huh?
Since when do we give medals to law enforcement when they shoot a mentally disturbed man?
I don't know if the shooting was justified but in the end, the dead guy didn't deserve death.
Since logic is not your strong suit let's review.
You know now that the nutcase was a mentally disturbed man. Mohammad Atta was a mentally disturbed man.
At the time the air marshalls shot and killed an imminent threat, neither they not anyone other than his wife knew for a fact that he mas mentally ill.
See the difference?
