I saw that advertised a while back and thought was a horrible thing to have. But then again, I had to think about it some more. I think I would probably won't one if I was to board a plane and saw someone suspisious and I may want one if I was walking alone in a parking lot to my car. There are definitely special circumstances where I think it might be valuable, but for the ones that would use it for the wrong reasons.....could be dissasterous.
