It's too late.
You can't cancel millions of weapons even if you do render them illegal, which no government, either state or federal appears to have the will to do.
Oh yes you can.
Australia did it in 1996.
They started by getting all the states together with the federal government after a mass shooting in Tasmania. They agreed to outlaw many weapons, and much tough regulations for those that were still available.
It took three and half months after Port Arthur, for those gun control laws to be passed, with a groundswell of bipartisan support from all sides of politics.
This happened because of the exact sentiment that's being expressed right now over Las Vegas. The exact same despair at the pointless and preventable loss of life that happened at a mass shooting gave politicians the will to change the law.
There was at first a straight gun buy back program. The federal government PAID people to return their guns before they outlawed them. They were then destroyed. There was an amnesty on any illegal weapons as well. You could just walk into a police station and over over a weapon no questions asked. Thousands of weapons were turned in.
And since then, there haven't been any mass shootings in Australia. None. ZERO. Is it really worth the price of you having the freedom to own a weapon to defend yourself when the cost is school shootings, the highest incidence of gun violence in the entire western world ? It's not talked about at all, but self harm in the US by gun is astonishingly higher than anywhere else in the world too. How would you having a gun to defend yourself have made diddly squat difference in a scenario like Las Vegas ?
None.
Why does the US have a gun problem ? Why do these numbers not horrify Americans even before Las Vegas ?
http://www.cnn.com/2017/10/03/americas/us-gun-statistics/index.htmlHere's a comic take that tells that story. But it's essentially VERY relevant to this debate. You'll hear the exact same arguments from Australian pro gun sides.

Rocket Launchers are very tightly controlled. We don't have mass rocket launcher massacres.
Hand Grenades are tightly controlled. We don't have hand grenade killings.
Military assault rifles are freely available and guess what....
