America’s greatest export is war. we’re a very violent nation. every generation since the founding has had a major conflict to attend - but most of our wars in the last 30 years or so havent involved a lot of “boots on the ground”. that pent up rage requires an outlet. mass killings/shootings/etc are a direct result.

adding to that, handguns are very easy to obtain - you can legally purchase them easily enough but there’s also a very active black market where cash is king and questions are not asked, backgrounds are not checked. since Americans are legally permitted to own/carry firearms (as enshrined in our founding governmental documents), the system cannot change. it’s not politically acceptable to request a change. no career politician is going to burn their entire life’s work in something that is destined to fail. even considering is is borderline insane.

dont expect things to magically get better.
