About the recent shootings in Buffalo and Laguna Woods, I'd like to point out where the blame lies. We no longer institutionalize the mentally ill and, having left them free to roam about and acquire weapons, we get mass shooting events like these.
It was known the young man who did the shooting in Buffalo was a sicko, and yet he was left free to perpetrate mass murder. I believe the same was true of the Laguna Woods shooter.
Actually, most of the so-called "lone wolf" killers are in fact "known wolves," people whose dysfunction has previously come to the attention of law enforcement. As they've not yet done something obviously felonious, law enforcement can't hold them and so they stew until they explode into homicidal rage.
Where guns are not available, a stolen vehicle is often the weapon of choice, or a selection of butcher knives or a baseball bat, or perhaps a golf club. An inventive Japanese used poison gas in a crowded subway.
Individuals like this occur in all societies, unfortunately, and our society has decided to allow them their freedom until they do something awful. Perhaps it is time to revisit this decision? I'd argue that time has come and past.
