Since most of us, even cops, are not involved in life or death shootouts enough to build up the experience, "contagious shooting" is understandable.
One thing would be possible, though. We have a Simunition training center at a local range, available to even casual shooters who are curious. Lazertag abounds, as does Paintball. AirSoft and 6mm paintball are readily available, cheaply, at most sporting goods stores.
It's possible, in the modern world, to gain a lot of "experience" without getting a lot of real bullet wounds. The military does it, especially for urban combat.
Perhaps the police should consider this, too. If an officer is considered to need a pistol with several large magazines on a belt, an AR, an a shotgun, as cops here even in good neighborhoods generally have, then that officer should be considered to need serious training, not just range qualification every year or two. It's not fair to the officer to send him/her out without such regular training.
When a cop was considered adequately armed when he had a .38 Special 6-shooter, I suppose range qual was good enough. But if there is now a need for the sort of armament carried by street cops here, then there is a need and an obligation to train them in the sort of situations where said armament is needed!
