Of course you have.
But NOW they're blaming the governments at all levels for not confiscating the Florida school shooter's guns.
So how about, the next time this sort of thing happens, we have all guns registered so at least we'll know what guns the psychos have when we go to confiscate them.
Another pathetic, confused, and dishonest argument.
By the way, when tyrants have taken power and confiscated guns, they have used the gun registration lists as their starting point.
If we had a good national database on reports of mental illness and if we required background checks for all gun sales, it would be extremely hard for a mentally ill person to legally buy a gun.
Why does the government need to know if a law-abiding citizen owns a gun?
