The Dallas 'Shoot-Don't Shoot' program uses 15 training personnel as actors, creating multiple live scenarios of police conflicts indoors, with shooting accuracy and reaction time judged by instructors. As only 40 officers can attend an 8-hour session, this training is expensive. The FATS system is a portable enclosed rack with a laser disc player, microcomputer, video projector, laser sensing camera and printer, revolver with primer-activated laser, and standard 10-foot projection screen. The laser disc holds 40 types of scenarios; 40 new scenarios can be produced each year. FATS displays on the screen where the first and second shots hit, the point value for the accuracy of the shots, the time the officer uses to respond to a threat, and whether the use of deadly force is justified. Freeze frame and replay functions, indoor and outdoor situations, and a record of session results in print are advantages of this system. The officer or a single instructor can operate the portable system, which can be used while officers are on duty. It is recommended that FATS be purchased and used as a supplement to the 'Shoot-Don't Shoot' training system. 4 tables.
