I agree that joint locks work well with persons who feel pain, but are limited in there effectiveness with anyone who is pain resistant unless you are looking at breaking bones and/or dislocating joints-things gotta be bad if you are using this type of force! As for gun disarms I feel they do deserve some attention. There is a funny story that I wanted to share that does have meaning for all LEO's and martial artists. I haven't seen the video but several of my co-workers have. A Border Patrol officer found himself on the wrong end of a pistol. He did everything correctly in his disarm-pushed the gun off line and moved his body parts out of the way in case the gun went off, disarmed the gun, struck the guy with the gun for a brachial stun.....then handed the guy the gun back just like he had trained to do over and over again! He had to disarm the guy a second time. The FBI did a study of officers shot in the line of duty in the 1970's (most officers used revolvers back then). Handgun instructors would yell at everyone that they weren't their mothers and the officers were expected to put their brass in pocket. Guess what happened during the real shoot outs? You guessed it-the officers took the time to put their brass in their pockets in the middle of the shoot out. Moral of the story-the way you train is the way you will usually do it when the poop hits the fan. You want to make your training as realistic as possible from start to finish when practicing. Another thing that I haven't seen addressed here is stress innoculation. In the old days before Tasers and Pepper spray we were stress innoculated early and often in the course of our work, but that first couple of times were real doozies. If we can get this type of training in the new officers before they hit the streets, and even the old timers, it is hugely beneficial.
