Moron.....the people selling guns to known felons are already breaking the law.....and they are breaking the law by not doing the background check on the known felons.....the felons already know they can't buy, own or carry those guns...already......
We already have laws that allow us to arrest all parties involved......the police already use sting operations to arrest people selling illegal guns....
Background checks are not part of any of that.....
But here's the problem with that position.
The Gun Industry encourages illegal sales by letting legal sales go on with very few restrictions. For instance, when they wanted to put a limit on how many guns you can buy, because you know darned well that if someone is buying 25 guns a month, he's reselling them to someone else in another state, the NRA went apeshit and opposed these laws.
The NRA WANTS criminals to have guns.
If they didn't, then all the Dick Tinys of the world wouldn't want guns, or at least not as many of them.
Much like the alcohol industry markets to drunks, the gun industry markets to gun nuts. The guy who bought a gun once in the 1990's and takes it out once a year to target shoot, he's not a prime customers.
