Police Officer casualty rates have stayed about the same for 20+ years.
Gunfights occur most often within 21 feet. And if you are going to be shot or killed, there is an 80% chance that it will happen within 21 feet.
Sight Shooting, which is traditionally taught to Police, is seldom used in gunfights.
Ad hoc Point Shooting is used, and with a hit rate of less than 20%, which shows a great need for Point Shooting training.
There are simple and effective Point Shooting methods, which are easy to learn and maintain with minimal training and practice. There is Threat Focus Shooting, Center Axis Relock, Pistol Quick Kill, and Aimed Point Shooting.
These shooting methods should be studied, and those proven to be practical and effective, should be incorporated into firearm training programs.
