I agree with a lot being said. I do not however see the value in requiring a degree from college as some sort of gold standard prerequisite. Some of the dumbest people I have ever met hold a degree from a major university. On the hand some of the worlds most brilliant and successful people are drop outs. For policing, your character, ethics, and aptitude are the most important attributes for the job. How do you handle pressure, how is your temper, can you make quick decisions under pressure, can you pay attention to detail and see the things others miss?
Lots of departments are requiring 60 hours of credits, not necessarily a degree. So you could go in for a BA/BS/etc., do 2 years, and drop out and you'd still qualify with the 60 hours required. Also, you're talking about people who dropped out of usually Ivy League schools, they're the exceptions to the rule.
What departments need is support, de-escalation training, and more community involvement. What I mean by that is start getting back to beat cops that know their neighborhoods. Nowadays most departments focus all their attention on traffic stops, which is basically just revenue collection.
I 100% agree that de-escalation training would be HUGE, and an incredible way to use some funds/time/etc. And knowing your community, and them knowing and trusting you, not just thinking you're out to ticket them for as much money as possible, as you said, would be huge too.
Coming from a family of cops, me being the only one to not go blue, I can say that the academy is most definitely more involved than barber school. My little brother, who went through 4 years ago, went through over a year of academy and then 6 months of patrolling with a FTO.
