Of course not, but it satisfies the talking heads and the idiots on both sides of the gun control debate, AND it helps the economy.
And the point you bring up is precisely why the existence of gun control, or not, does not matter ONE bit to the people that REALLY wanted the guns to kill. Just want to reiterate that so the idiots clamoring for "gun control" without even offering a solution can somehow understand (aside from "get rid of all guns"), or realizing what that would do, both from a civil liberty point of view to defensive contingencies that may arise.
Look at it as the same process as getting your drivers license, you NEED to be certified before you can buy a gun. Your constitutional rights can be denied if you have a criminal record, so much for that, right? So write into the bill the exact denial criteria, it isn't that difficult. Think.
A drivers license and right to bare arms are two different things. And we already deny criminals the right to purchase weapons. So what does your plan do outside of harass and deny law abiding citizens the right to bare arms? And more specifically. How would it have stopped these people yesterday?
So you make the process more difficult to own a gun. These mass shooters either go through the process, get a gun, then kill. Or they bypass it all together. Rarely do mass shooters have any kind of history that would deny them the right to buy a gun. Unless you want to expand reasons well beyond breaking the law. Which is a nice big slippery slope waiting to happen.
