When there's an uptick in violence, you have to look at potential causal factors which affect behavior, not coincidental non-factors.
Let's see...
-- millions of people have been vaccinated and received one or more boosters with something that has no long-term clinical studies, and which have coincided with upticks of unexplained sudden deaths.
-- the pandemic and subsequent loss of job, lack of access to school, fear of going out in public including clinics and hospitals, quarantines, lockdowns, mask mandates and so on have contributed in increases in stress-related mental problems. Being cooped up for months with the same people and nowhere to go plus financial troubles can cause severe stress.
-- political divisiveness has caused stress, fueled by some very significant court cases such as the overturning of Roe v. Wade and the reversal of unconstitutional state gun control laws under Bruen.
-- social media bullying, lack of dating opportunities, deteriorating marriages, loss of investments & savings, etc, etc
So many potential influences on behavior, it gets complicated. We have to treat each case independently to get answers. Pasting a tidy "too many guns' trope on every shooting not only supports a non-solution, but it masks the real reasons for which nobody seems to want to find solutions. it's just another opportunity to push an anti-gun agenda while ignoring the motivations and reasons that were the actual cause.
