The cop had no choice about the setting, he had to follow the shooters wherever they went.
He should not have fired through the windshield though. There’s no telling where those rounds will go after punching through thick glass and laminate.
He started to fire lefty and then abandoned that idea. Don’t cops train in firing with the off hand?
...”He should not have fired through the windshield”....
Well if you had steady live fire coming at you through your vehicles windshield to try and kill you you might think differently. In less of course you’re fool enough to stick your head out the window.
Actually firing through the windshield is a legitimate technique and trained in some quarters.
