Nope....what you want, according to your logic is to ban all drugs.....if we follow what you want for guns....that is where your logic leads..
We have all the laws we need on the books.....what happens? The democrat party judges and prosecutors keep releasing the most violent, repeat gun offenders over and over again....they are the individuals doing almost all of the shooting and killing, primarily in democrat party controlled cities...
The laws you want to add.....do nothing to stop them........you keep pushing Universal background checks...would not have stopped this felon since he already could not buy, own or carry the illegal gun he had, and then sold, without a background check, to another illegal individual...
The very thing you want, would not have stopped this transaction...but, it would put normal gun owners in legal peril if they lend a rifle to a friend without taking them to a gun store to get a background check.....turning law abiding gun owners into felons...for the simple act of lending a gun to someone they know....
At the same time....the only reason you actually want universal background checks, since you already know they don't work....is so that later you can demand gun registration.....which you need when you get the power to ban and confiscate guns...
