The fire department are the real OT scammers! They work two back-to-back 24-hour shifts. What they commonly do is trade days with their colleagues and work FOUR days straight. That's 48 hours of OT in 1 week! Even though their base pay is lower than police, most of them make more in a year because of OT pay. Speaking of Fire, they are a way more discriminatory organization than police IMO. They're a real "old boys club" and almost all white males, with a few black sprinkled here and there. They rarely hire for attrition because it's less opportunity for OT. The hazing culture is like police departments were back in the day. Still, they really have it good. I'm jealous of them.
I agree with the decriminalization of drugs. Recreational marijuana is already legal now, and other drug offenses have been lowered from felonies to misdemeanors, or misdemeanors to infractions. Though according to your 2nd chart, opiate deaths didn't skyrocket until after 2007 where the 1st chart ends. But nonetheless drug possession and abuse is more of a health issue and shouldn't result in the mass incarcerations we've seen for the past few decades.
I understand a lot of people will have an issue with the amount of OT pay for police, but I've been on the job long enough to see other scams like workers comp (staying home for 1 whole year full pay), extended and questionable leaves of absence/sick days, able-bodied police officers doing civilian/admin work, frivolous complaints/lawsuits of discrimination/harassment/racism/sexism/retaliation with significant pay-outs, suing the department for injuries/illnesses with again more pay-outs. And the best one : https://www.latimes.com/opinion/editorials/la-ed-drop-pension-20180206-story.html
Of course I'm biased, but I don't mind the OT because at times it's necessary due to the nature of the job. And a lot of the special OT assignments are not paid by the department anyway. I personally have a bigger problem with my colleagues who, although grown-ass men and women who call themselves cops, are always scamming and crying or playing victim to get a lawsuit or promotion/special assignment. It goes against what I stand for.
