It is the real world in many places. "Criminals" are not a homogenous group. Petty criminals will not usually be making the effort to get a gun if getting a gun is inconvenient. Some high level criminals will find ways to get guns but the number of criminals with guns will be much lower with gun controls.

It’s not your real world, lots of other countries have so little gun violence that a shooting makes the national news when it happens and thats maybe once or twice a year.

I'd say there is no country in the world that proves this point of view is a success in any metric.

"You can never ban all guns, so don't bother banning any guns. It makes no sense to reduce gun violence if you cannot eliminate it completely."

> Criminals will always find a way to get guns [...]

In that case, how about the cops can just shoot anyone with a gun who's not a cop?

Should keep things pretty simple, and the majority of the population in the US would be a bunch safer. :D
