Again, like their DougCo backing of the kock bros, this editorial board has it wrong. 

We do not need BETTER GUN LAWS. 
What is needed is not regulating the guns, BUT, regulating who can buy and own firearms and accessories. 
This idea that you are going to regulate firearms is ridiculous. You really can not. 
BUT, we can require that owners go through levels of training and vetting. 
That would do a lot more for stopping nut jobs. It would not stop all, but columbine and aurora theater would not have gone down like it did (though to be fair, those killers might have simply choosen to switch bombs or other means).
