I got it from a several people in my life who've known people who attempted to become cops, who got turned down for having too high a score in intelligence on the entry tests.Idk what departments you are talking about but every department I tried to get with wanted the best and brightest.
Especially the sheriff's office. They had you do like 4 interviews to get it.
And...*Looks at the cop who almost died to a woman basketball player with a knife in a crowded hallway*
Or...I could pull out the large amount if cases that have had innocents get in the way due to policies that restrict cops.
Oh, and departments with bad shooting are often due to lack of training due to funding.
Or be like NYC and have a 12 pound trigger pull
One of them ended up becoming a Forest Service employee, because the Forest Service aren't normal cops and don't just want authoritarians in uniform, like most depts do.
