I don't think it is going to happen, I think it is going to get worse.
As for some of the other comments, I don't think police should be trying to shoot guns or knives out of people's hands and the rest of the Hollywood nonsense, but I also think it is incredibly delusional to train to shoot someone to the deck with a .38 Spec., 9mm, .40 Cal., or .45 ACP, center of mass, and think you're not training to shoot to kill as opposed to the politically correct, "shoot to stop." Yes, you are shooting to stop the threat but the P.C.-B.S. inherent in the statement is the most effective way to stop, i.e., neutralize the threat is to kill the person or put them at death's door instantaneously. I won't get involved in appeals to authority or other stupid debating practices, this is reality to me and everything else is just feel-good nonsense. If you train to shoot someone center of mass multiple times until the threat is over, you can call it "Snow White and The Seven Dwarves" or some other Walt Disney title, you can call it something out of the Kama Sutra, I don't care. It's shooting to kill as far as I'm concerned and to claim otherwise is a complete and total disavowal of what bullets due to lungs and hearts.
