Huh, pretty kool IMO. I love the idea. I can only hope it's cheap enough for the common man who wishes to do so. As for the idiots who think this is going to make them more unsafe, well, there's no arguing with them or a need to. If ALL guns were somehow collected and destroyed the bad guys would still have them some how some way so safety is not the issue training and owning one is. Oh, and for those people, when seconds matter call a cop...... they'll be there in a matter of minutes.
