I was being a bit facetious in offering up the .22 caliber example. It is an example of misuse of course and illustrates the point that "data" accurate or otherwise can be used to argue a point that may very well be contrary to the greater good. Take a look at homocide statistics, use of deadly force statistics, and LE deaths by gun fire statistics starters. That should help you more clearly define the problems. From there, working towards constructive solutions that don't unreasonably limit the freedom of law abiding citizens is the task at hand.

Personnally, I think we should all be free to carry and own whatever we want and solutions should be aimed at the root cause of the problem, not the tools that the problems choose to employ.
