That's my question also. Being older than most here it's a stark reality for me. Something radically changed in the last 50 years. Drug use and mass shootings weren't all that common 40-50 years ago.
I did notice that the WaPo has published more than one article about the AR-15 and mass shootings in the last few days. I haven't read any of them yet because I know I'll disagree with most of it, but it's there if anyone wants to read it. I'll probably read it in the next few days.

Escalating arsenals: In response to years of right-wing violence and intimidation linked to the AR-15, some far-left activists have begun to form armed groups, billed as community defense, often turning to the AR-15 as their weapon, as well. Some leftist activists who long favored nonviolence have grown more tolerant of armed support at public events as threats against the LGBTQ community and other vulnerable groups rise and faith in law enforcement recedes.
