Makes me think of the remark of a US politician after what happened in Virginia Tech, maybe it was Bush but not sure: teachers should have a weapon in class to defend themselves.
Ok, now why in Europe, in countries more or less demographically and socially similar to US, like France, UK, or Germany, people don't have that claim? Why in the same time the criminal rates are higher in US than in these countries in which people can't have that wonderful defense that is a firearm? What is that?
Take your pick as to the underlying cause of crime in the U.S. (drugs, socio-economic, etc), but it's not the ownership of guns by law abiding citizens.
Oh and skip the OMGZ WE NEED TO GET RID OF GUNZ CAUZ OF MADMEN1111! That rallying cry is old an boring. If you want to go down that road, ask the families on the Long Island Railroad massacre if they wish their loved ones were allowed to carry? That guy would have got one shot off in Texas, that's why he went to Long Island. He knew no on e would shoot back.
