I'm not a policeman, but used to have a car four cell Maglite, would also toss in suitcase for out of town tricks. I finally got tired of lugging the thing around.
I went back to basic concept of flashlight, to provide light. Now I carry a plastic Everready Industrial. It is light weight, can slip into pants pocket if I need hands free, and provides gobs of light.
I train a few strokes with it as a yarawa (spell?)stick,but really just want to use it as flashlight. No lawyer in the world can say it's a weapon.
