It sounds like the detective was a pedophile, and seized the opportunity to be a predatory pervert who felt he was protected by his station. The shocking thing is that nobody else stopped this whole thing before it got that far.

OfficerS. With an S. Multiple. That’s what gets me. Not one of them spoke up and said, “Hey, uh, I know we’re collecting evidence and all, but let’s step back for a moment. We’re ordering a minor to perform a sex act in front of us while we film it. Are we sure we’re not the bad guys? Can we take a minute on this?”

and then the lead, himself, is investigated for same. THAT is the kicker!
