I've noticed a massive increase in the amount of bullshit blissninnys shrieking for the immediate total ban on "assault weapons," after 12 people were murdered and 58 wounded at Aurora, CO. Folks, the plain and simple truth is this: You are NOT going to stop mass murder by outlawing guns. Period. Full stop.
Timothy McVeigh didn't use a gun, he used an ANFO bomb in a moving truck. He killed far more than this cowardly fuck did. The 9/11 terrorists used boxcutters to 'jack 4 airliners and killed a couple thousand innocent people.
Despite all that, even if you outlawed weapons completely, since when the hell have bad guys ever went "OH SHIT, this gun is ILLEGAL for me to own/possess!!! FUCK, so much for that murder spree I was about to do. "
Guns are effective weapons. The greater majority of firearms are possessed by law-abiding people. Taking away all guns will remove them from the hands of the law abiding. This will NOT stop these incidents. Only people willing to fight back in any way they can will do so.
