Are you suggesting that the GCA is the CAUSE of the increase in gun violence? Seems to me to be a correlation at best but not a cause by any stretch. A lot of things have changed since then, a lot of things have stayed the same. Did gun violence spike in 1968? I think you'd be hard pressed to make a convincing case that the GCA is THE cause. It may or may not have contributed.
Here are a couple of timelines showing violent crime (not gun violence) as a function of time. This one shows the increase beginning around 1963, prior to the GCA.

So, am I understanding your position correctly or have I misread it?
This is business troubleshooting 101.
Things are running fine. Yay. You keep things the way they are.
Things are no longer running fine. Boo. You look for what changed. You roll back the changes.
There will always be someone willing to tell you that "the changes were necessary" or that "reverting things won't make any difference" or possibly that "things are so different now, we dare not take them back where they were."
Fail.
You revert the changes. You return things to the way they were when things were running fine.
Now, there's a common false argument that targets some unrelated change -- like equal rights for [insert race here] -- and assert that since you want to roll things back you must want oppression for [insert race here]. It's false logic of course. If you're fixing the customer flow in a restaurant by rolling back the [new] seating arrangements that screwed things up, you're not also proposing to do away with improved sanitation.
The issue is guns and gun ownership and gun rights and things pertaining thereto. And, while it's easy to argue that "correlation =/= causation" you don't sit and squabble about the "reasonableness" of it all. You just roll it back.
There was an event that triggered the GCA 1968, and it wasn't a mass shooting. It was a bunch of black people standing up for their rights and doing it with openly carried guns. This terrified the politicians, so they did the only thing they know how to do: make a law, and try to structure it so that it impacts the target group without actually naming them.
They wanted to ensure that guns would only get into the hands of the "right people," but they couldn't actually articulate who the "wrong people" were. And, of course, as happens any time you paint with too a broad brush, you screw things up for everyone.
But you can never just admit you were wrong and repeal the law. Everyone knows that laws are infallible. If it isn't working, then clearly what's needed is some more laws to help out the poor overworked law that's struggling to make things right.
And so, more than 20,000 laws later, it's worse than it ever was, and the only thing politicians can think of is . . .
MORE LAWS, DAMMIT!!On the other hand, anyone trained in business analysis would immediately ask, "why the hell do we have all these stupid laws; they're not working, so why do we have them?"
