I was taking my CPL class today and the instructor mentioned that if you use a gun with a laser sight for SD the prosecutor could turn that against you. The argument was that if you had a laser and could have hit your attacker where you wanted then you could have easily avoided killing him. I understand how a jury could see things that way. Not to mention you don't learn anything by training with them. I thought that was worth passing on since I hadn't ever considered that angle and we seem to have several people asking about laser grips from time to time.
