When I see several of those European countries on the news today, I see pairs of police carrying assault weapons to defend their populations after the terrorist attacks by the 'peaceful Muslims' the invited into their countries.  Even the Brits have increased their number of armed officers.  

Your peaceful non-gun owning European world is changing to meet a new threat.  

Disarming our citizens is not a solution to the gang wars in our inner cities or the idiots like these three in Podunk Springfield.  And it is not going to happen.
