What difference does it make?
I have always suspected that a lot of these SWAT teams are populated with trigger-happy Rambo types who are trained to shoot first and ask questions later.
Fire discipline? They’ve never heard of it. Unlike private citizens they are not accountable for every bullet that is launched from their weapons.
Its a lot more fun (and safer too) to roust private citizens from their homes and force them to keep their hands over their heads after they’ve been frisked 3 or 4 times.
And kill dogs.
