I did a quick deep dive into mostly school shootings and/or school age shootings and there seems to be quite the uptick in school shootings following the covid shut down. Many seem to blame the mental and behavioral decline of students returning from the pandemic/shut down. Gun sales also soared in US during the pandemic! School shootings soared after the pandemic and are holding steady, whereas, adult shooting rates returned to pre-pandemic levels starting around 2022...again, this was just a quick research that I did, but I do believe the shut down greatly affected the mental health of young people, and to some extent adults; mixing in the high access to guns.
Mental health is obviously (to me) a problem in our society, but personally I would like to see another ban on assault weapons. One study showed that 1/3 of mass shootings (defined as four or more shot and killed) and 52% by handguns...however, a majority of the deadliest shootings involved assault rifles. (one report said 85% of mass shooting fatalities were the result of assault rifles). Further, mass shooting homicides in the US were reduced during the federal assault weapons ban (1994-2004)
just my two cents...
