On CNC3's the Morning Brew earlier today Hema Ramkissoon spoke with Inspector Michael Seales about a police shooting in San Fernando.
Mr Selaes said the suspect broke the 21-foot rule and officers had to defend themselves.
The 21-foot rule was developed by Lt. John Tueller, a firearms instructor with the Salt Lake City Police Department. Back in 1983, Tueller set up a drill where he placed a "suspect" armed with an edged weapon 20 or so feet away from an officer with a holstered sidearm. He then directed the armed suspect to run toward the officer in attack mode. The training objective was to determine whether the officer could draw and accurately fire upon the assailant before the suspect stabbed him.
