The problem with the gun control crowd is they differentiate between gun related crime and crime in general. Getting rid of knives would reduce knife related murders, but banning knives doesn't get rid of knives and murder is murder.
Your ilk tend to use misdirection and smoke and mirrors to make it appear as if you might have a case, but the fact that your ty arguments only surface after tragic events shows that, at the foundation of your argument lies a collage of illogical conclusions that, without the emotional jargon and the energy of the moment, are completely toothless.
When your argument is sound, it won't rely on tragic events to sway opinion. It will be true regardless, but your current argument isn't true ergo you rely on the energy of the moment.
The rantings of ignorant liberals like you don't move me in the least, because you are too uneducated in the facts of your cause to even be a threat. You're reduced to searching the internet for material to support your naive claims.
The idiot in Aurora would not have tried to kill people with a knife. Had he not been able to acquire a gun, he would have used a bomb. Someone who plans for months to kill people including booby trapping their own home with BOMBS will not hesitate to kill as many as possible, if that's his goal. This guy wasn't looking for numbers, he was going out wth a bang, He wasn't mad at people, he was convinced he was a villian and wanted to do what they do. He could have burned the place to the ground.
