Having grandchildren of school age I attend related functions on a regular basis where of course carrying a weapon is a felony. I shoot on a regular basis and attend defensive pistol classes throughout the year so I feel fairly unarmed carrying nothing but a can of pepper spray and a swat t tourniquet in my pocket. Do any of you law enforcement guys have any recommendations on non lethal defense sprays such as strengths, applicator type, how to train, etc? Other options such as tasers? Electrician by trade, I know for a fact that an unexpected pop and a flash from a panel box will clear a room. Guess I'm looking for some first hand experience on effectiveness besides just reading the ads. Many thanks.
