Or is the solution to "a huge and deadly" problem made it worse?
Prohibition has a poor, poor history in this country.
If you want to "do something", how about reducing poverty and increasing affordable access to stigma free mental health with no gotchas like seeking help for your depression and ending up on a list that follows you around when you go to get a hunting rifle or a job or may end up being used against you in ads if you ran for office.
Of course often "doing something" is actually doing nothing and zealously pretending you did like the goofy ass assault weapons ban that played around with cosmetic features, I assume to annoy consumers, but otherwise would not impact the situations it was supposed to reduce.
There was a poster yesterday who wanted to "do something" by restricting the number of weapons a person may have on them but was unable to explain how this would make a massacre less likely to happen. There is no expectation that such an initiative would actually impact the situation used to justify it, the point cannot logically be to "do something" about the problem because there is no argument it does.
Nobody is going to ever, not once in a billion times, going to be like I was going to commit mass murder but the law says I can only carry one gun, whatever shall I do about this dilemma?
When efforts do little to nothing to resolve the problem but serve to hamper law abiding, tax paying citizen you force them to be less receptive and "reasonable" to your way of thinking.
