Interesting thread! Coming from a law enforcement background and a current Defensive Tactics Instructor I think the strike bezels are extremely useful! The bezel can be used in 3 different fashions. 1) If you want to allow the light to continue operating, bezel down, without over heating, 2) allows the user to direct, not strike, a person to the ground. I have used this method with a male who was uncooperative and resisting arrest. I had my M2 (with GG&G TID) in my hand and placed it on the center of his back and forced him to the ground quickly and without injury! 3) The strike bezel, as a last resort, could be used as a weapon to strike at the face, arms, hands, or any other fleshy area! I emphasize as a last resort if you have no self defense training I would suggest trying to put some distance between yourself and your attacker. If worse comes to worse than immediately strike for the face! If you take away your attackers ability to see you will be able to get away or at least gain some distance to a safe area! Hope this helped a bit! Be safe out there!!!
