Come up with answers. Now. Beginning with the return of an assault weapons ban.
We know: That label doesn’t actually describe a clear class of guns. And that some studies show that the last ban, in effect from 1994 to 2004, had a limited impact. But that simply means the next ban should be better written, with a clear definition focused on factors like firepower — rate of fire, muzzle velocity, etc. — not on cosmetic features.
The Supreme Court has ruled that the Second Amendment protects the right to own “guns in common use.” That doesn’t cover the semiautomatic weapons regularly used only in mass shootings.
This ban would only be part of the response: Keep improving background checks, find wiser approaches to mental health, get every state to pass a red-flag law (do a federal one, too, even if issuing these restraining orders is mainly the job of state courts).
