I've summarized: 1) felony to sell, offer for sale, or possess any weapon or device that emits electrical current, impluse, wave or beam which is designed to incapacitate, injure, or kill 2) must be licensed by state to use a laser for dermatological procedures 3) use of tasers are an exception for those in law enforcement and a few other security related or homeland defense professions Notice that the law in my state prohibits 1) selling, 2) offering (for sale), and 3) possession. I.e., you don't get to have a high powered laser, maser, microwave gun, etc. legally. Notice that there is no exception for law enforcement or military for lasers, masers, microwave weapons, etc. There is an exception for tasers for law enforcement. Like I said, "legal no-no". As I recall, *all* the other states have had similar laws since the 1950's. I looked into this quite thoroughly a few years ago. Rod Pemberton |
