I have used a 3 C cell Maglite for a number of years. I find it to be very portable as well as quick in a defense situation. I think its use should be confined to defensive moves - blocks and locks - as opposed to strikes. Striking a subject should be a last resort but should be as with any other baton; aimed at long bones and joints. As for criminal liability, the type of weapon doesn't matter as long as you can articulate that you were defending yourself. It is only a flashlight after all
