A sad truth is a truth nonetheless. Most police officers, when they report to the academy, have never fired a gun. For most cops, the only gun they’ve every fired in their duty sidearm, and maybe a few rounds from a shotgun or carbine. At the academy, they are trained to a level sufficient to pass an extremely easy qualification course, and then the vast majority never fire their gun again unless you absolutely force them to. This is not to ignore the fact there are a small percentage of police officers who are, in fact, great shooters. But (a) they are hugely in the minority, (b) they’re not great shooters because of the level of training they’ve received from their department, they’re great shooters because they’re enthusiasts who’ve worked their butts off to be that good. When it comes to “the police will protect you,” for numerous reasons the well-trained, dedicated, highly skilled gun carrier is far better off protecting themselves.
