Like I said your original request (statistics of “legal” CCW permit holder, without premeditation, discharging a firearm, in California) is incredibly specific, making it very difficult to find quality research. But here’s what I was able to find for you:
Johns Hopkins has this: https://publichealth.jhu.edu/2022/study-finds-significant-increase-in-firearm-assaults-in-states-that-relaxed-conceal-carry-permit-restrictions
This one includes some good details as to why these studies are challenging, and what causes errors in the data: https://www.rand.org/research/gun-policy/analysis/concealed-carry/violent-crime.html
Here’s a summary from GVPedia (note the sources in the footnotes): https://crimeresearch.org/wp-content/uploads/2022/02/GVPedia-Permitless-Carry-Factsheet-Feb2022.pdf
Hopes this helps.
Yes. I think it’s especially important for attracting (or perhaps more accurately, maintaining) new users to the fediverse.
