Over time, they think that guns will become less and less common, and we will not need to fear violence from those with firearms.
that is an understandable ignorant fear of many in the general public. But the politicians are working on another premise, and it isn't about setting up a tyranny. it is more simple: the stock and trade of politics for thousand of years is distraction and scapegoating. They cant solve the problem of crime but they can go after the low hanging fruit of legal gun owners
