Just like getting a drivers license, there should be some form of aptitude test as well as psychometrics. If you're not intelligent enough to pass the test, and/or you're deemed psychologically unfit you don't get a gun, and as Mindy said, annual renewal of your registration. I've really never given it any thought and I don't have all the variables in front of me, but that would be an improvement. It's always been just a bit insane as it stands with just background checks for felons.

I never thought I’d say this but thank god I live in Florida

Me too.

Okay, I suppose as an ignorant Irishman I couldn't comment without knowing what exactly the checks are? I mean, I assume there isn't a box for you to tick that says "I intend to use this in a mass shooting" or "I will kill my neighbour when I get home" or whatever. So what questions/checks are in place?

In Florida they ask your name, you show your ID, and come back three days later and buy whatever you can afford. The only ones they deny are felons. You can be crazier than a bag of angel dust. If you got a name and an ID and money you can buy enough guns to arm Uganda.

What have they got against cats having guns? Oh. OH! FELONS....

I know it's not possible but I voted to ban all guns.

Americans simply cannot be trusted to behave so it's the best option.
