You can see at the end of this video how freaked out this cop was, he couldn't reload his pistol for shit. That reload ought to be smooth as silk, just 3 movements in under a second.
Of course, you can also see that his windshield shows how badly he was aiming at first. An inch between shots a foot away from his pistol? Is 10 or twenty feet between bullets by the time they are anywhere near that SUV he was trying to aim at. That means those bullets were not hitting the SUV they were going on past it and hitting the neighborhood at random. WHY is he jeopardizing the lives of the people in the neighborhood?
His fumbling around for at least a 5 count, when he ejects the magazine with the wrong hand, and load a new magazine with the wrong hand, is so absurd. He's lucky to be alive, as those morons trying to kill him are probably a hell of a lot faster and smoother with a reload. He ought to able to fire every bullet he carries on his uniform with accuracy in under 30 seconds including reloads.
