According to Annual FBI crime statistics "hammers" & "clubs" KILL, themselves, autonomously, with no human input whatsoever, more Americans than rifles of every variety combined. http://www.fbi.gov/about-us/cjis/ucr/crime-in-the-u.s/2011/crime-in-the-... It's at epidemic proportions, I can't even feel safe with my children walking out of our unfinished gated community, fearing some underpaid proletariat might MURDER them...
YOU SHOULD BE AFRAID TOO (or else taking your right to hammer & club ownership becomes much more difficult)
Anyway, with all my self righteous "liberal" pomp, I'd like to use my fear to justify taking your rights away.... I know not in the good ole U. S. of A.... But reefer madness worked, so why not?
