The US ranks 31st in the World, not 1st, for gun-related deaths.
If you're talking solely about murders committed with guns, there are 82 countries worse than the US, and some of those countries ban guns.
Gun-control does not reduce crime or gun-related deaths, but Culture does.
Guns are smuggled across the border from Mexico, and smuggled by boat on the East and West Coasts, plus the Gulf Coast.
Many criminals commit crimes with guns they did not legally purchase, because they obtained the weapon on the Black Market, which would expand in size if guns were banned. They only thing you'd accomplish is leaving good people defenseless against criminals.
Liberals have strait-jacketed the rest of us, so that we cannot force the mentally ill homeless, or any mentally ill person to take medication, and we cannot force them to live in a group-home or other institution, and we cannot force them into treatment of any kind, so they're left to their own devices.
And then we have certain Conservatives who think disarming the mentally ill violates the 2nd Amendment, in spite of the fact that the Framers of the Constitution only intended for law-abiding citizens of sound mind to have weapons, and the 5th Amendment's Due Process Clause requires the State to prove that a mentally ill person should not be armed for the safety and peace of all.
Hold on a damn minute floorist.
The GOP has been blocking mental health funding since frikking Reagan was in office.
