Its the dumbest idea I've seen in a long time / and I'm offended especially the closer I get to retirement age.... ( Just because I'm not as fit as I was 40 years ago / doesn't mean I can't defend myself with a 1911 or any other weapon I choose to carry ) / or a crescent wrench for that matter if I choose to.
That thing would be like taking a Dull 2" pocket Knife to a Gun Fight ....
If I live long enough that this thing is the only option I have for self defense, I trust someone will wheel me close enough to one of those dumb-asses and let me smack the smirk off their faces.....my word this concept is offensive and lame.
