An overlooked blight on our education system.

Most of the abuse never gets reported. Those cases reported often end with no action. Cases investigated sometimes can't be proven, and many abusers have several victims.

And no one - not the schools, not the courts, not the state or federal governments - has found a surefire way to keep molesting teachers out of classrooms.

In fact sometimes the public schools enable the sexual misconduct.

The AP discovered efforts to stop individual offenders but, overall, a deeply entrenched resistance toward recognizing and fighting abuse. It starts in school hallways, where fellow teachers look away or feel powerless to help. School administrators make behind-the-scenes deals to avoid lawsuits and other trouble. And in state capitals and Congress, lawmakers shy from tough state punishments or any cohesive national policy for fear of disparaging a vital profession.

That only enables rogue teachers, and puts kids who aren't likely to be believed in a tough spot.
