The quote from the guy who did the technique, putting it into context...
This is a demo Technique meant to " be cool" and surprise the inmates when they are trying to pull the trigger before I move. The biggest critique is that my head does not move to get out of the line of fire. Here is the logic, the left hand comes up from the blind spot of the attacker holding the weapon, (IF) executed correctly the parry is the redirect which moves the line of fire from defenders head. 1. Best case scenario the strip works threat eliminated, 2. most likely case the weapon fires intentionally or accidentally and powered blast and percussion of discharge temporarily deafens defender but he has control of weapon now. 3. worst case attacker keeps a 5 -8 ft distance and unloads a clip in defenders chest and head, reloads does the same and then dismembers defender and shoves him in a black garbage bag to dispose of body.
