When ever corruption scandals breaks, I always notice two things:
1) The "blue was of silence" is more fiction than fact. Sure, cops in collusion won't talk, at first. But that's hardly a blue wall. I mean, given people's natural inclination not to snitch on their friends and family, cops snitch on other cops quite regularly. Probably more so than other occupations. Why? A) cops don't like bad cops, B) when push comes to shove, people CYA and say "I'm not going to risk my pension for that dirty cop I never liked anyway."
2) The dollar amount some cops are willing to screw up their lives, their reputations, and their valuable pension. It's chump change. Lazy cops retire. Bad cops retire. But dirty cops rarely retire because being able to rat out a dirty cop is a great get-out-of-jail-free card. And that card is something other crooks find very useful. I mean, just put in 20 to 25 years and they pay you for the rest of life! And you screw it all for $100 here and $200 there?
But here we go, as reported in the Times: "One detective was allowed to pay $20 for an encounter with a prostitute that would normally cost $40." A cop gave his all for $20 off a blow job.
This was a "multi-year NYPD investigation" started by a top from a cop. But a multi-year NYPD investigation means there are a lot of well crossed T's and beautifully dotted I's.
Last I heard, 7 cops and about 20 civilians were arrested.
It's also interesting when internal PD investigation brings down dirty cops. Cops are like, "Great, system finally worked! Stupid dirty cops got what they had coming." Cop-sceptics are like, "Blue Wall of Silence is proof police are irrevocable corrupt!"
Also, for police and sex-workers alike, prostitution should be regulated and legal.
