My first thought as well: they didn’t bother to differentiate between legal carriers and criminals or it would have disproved their assumptions!
BINGO! Great minds think alike. I chased down this study and read most of their boring statistical analysis.
I could not find anywhere that they cared whether the guns were LEGAL or not. Some gang banger with a gun buying drugs from another gang banger with a gun in downtown Philly doesn't mean anything to me as I would never be kind that situation. Not even HALF of that situation.
from their study:
“It is also worth noting that our findings are possibly” (POSSIBLY?) “not generalizable to non-urban areas whose gun injury risks can be significantly different than those of urban centers like Philadelphia
NO KIDDING Sherlock.
This study is totally meaningless unless you are an unemployed, low life, Black, drug user or boozer, living in a bad neighborhood in downtown Philly. Unless those statistics apply to you, this study doesn't.
