I think the quarantine is for information in this case. Instead of breathless, stop-the-world coverage of these events, treat them like traffic accidents: “22 people were murdered by a white supremacist terrorist in an El Paso Wal-Mart this afternoon. Now here’s Bob with the weather.”

Gun buyback programs are 1 kind of medicine. Some people won’t take it, but we should try. Maybe we can institute some kind of guns-for-Medicare program (only sorta joking).

Gun control legislation is the inoculation. I don’t think we can get to full-on prohibition in the US without repealing the 2nd amendment, but we can implement licensing and registration requirements and longer waiting periods.

We also need to improve the existing systems. The ATF has a “gun registry”, but it’s not a searchable database. See https://www.thetrace.org/2016/08/atf-non-searchable-database...
