Tasers are very illegal in many states, they are also not completely L-T-L. Especially if the person is wet, has a pacemaker, ect. It also relies on batteries being charged and kept topped off. It isn't something like OC or L-T-L shotgun rounds that can be bought and left alone for years until it is needed. Also, they are one shot only unless you keep changing the front piece, many people can get up again and keep fighting a few seconds after being hit, and they arn't very accurate.
