So they never drive out to the desert to shot rocks ? Never went hunting ? Fresh from the range.
Its hard to stop a well trained person who just snaps one day.
Thats not what were seeing.
I havent seen anything that says the El Paso guy was in the service.
He was practicing.
He even mentioned how hot the barrel became after putting 100 rounds through it.
This isnt a guy who just snapped one day.
