From the article:

"All told, the AP determined that some 550 officers lost their licenses from 2009 through 2014 for sexual assault, including rape, pat-downs that amounted to groping, and shakedowns in which citizens were extorted into performing favors to avoid arrest. Some 440 other officers were decertified for other sex offenses or misconduct, including child pornography , voyeurism in the guise of police work and consensual but prohibited on-duty intercourse.

About one-third of the decertified officers were accused in incidents involving juveniles ."

These are just the ones who got caught; I would imagine such compromised officers have little interest in enforcing laws against other sexual abuse offenders.

Aahhh! PDF warning!
