What is missing in all the hysteria is some sane pol or talking head to cite the numbers of times average citizens use guns for self defense. Even if it's only one tenth of the claim by some people (two to three million times annually), citizens use them for legitimate self defense far more often than a nut goes off killing people.
No matter what feel good measures are taken, there will be senseless mass shootings/killings in the future. It might not even be a gun. Killers have discovered that motor vehicles work just fine in slaughtering innocents.
Leftists are determined to abolish or gut the 2nd amendment. They must be stopped.
