In Arizona we had a problem with a few people turning flashlights into bombs. A few people have been injured by them. To this day some thrift stores won't take in any flashlights for the fear of them exploding.
@Lazerbeak - No worries none taken . I have to admit that it is pretty funny seeing a photo of a flashlight with cops and such around it. I'm just glad we haven't had an occurrence in a while and I hope it stays it that way.
