But it would still take a lot of effort to get a gun, and a lot of people who commit gun crimes aren't career criminals who would put that much advance thought into getting a gun if it wasn't so easy. Sure the Bloods and Crips will still have and be able to get guns, but they're not currently getting into shootouts with everyday people. What disarming the general population would do would be to prevent the regular dude who just snaps and shoots someone because he would normally get in a fistfight with them (or just even give them the finger) but instead shoots them because a gun is nearby and he is really pissed and not thinking clearly. And I think those types of pissed off shootings are far more common than actual premeditated, planned-out shootings. So I think most people not living in criminal circles would be safer.
You remove that random guy gets so pissed off that he gets his gun and kills someone shooting. But you also remove all self defense that a gun owner has. You give criminals near 100 percent certainty that if they show up at your house at night that you will be unarmed.
I don't think this is a worthwhile trade. I think that the guy who snaps and is willing to go and get his gun and shoot you, but is not so angry that he will find a lead pipe or a knife or will wait for you with his car to run you over is a pretty small percentage of killings. Most likely a guy who would do that is rather predisposed to committing a violent act anyway.
