They stay on the job in exactly the same way that predatory priests stayed on the job. Sympathetic superiors, many of them compromised themselves, turned a blind eye, quietly moved the problem cases around when the heat started to build, and justified their negligence by claiming that they were defending the institution.
That’s exactly right. However statistics show that the number of reported abuse and abusers in schools overwhelmingly dwarfs the number of predatory priests and reports of abuse by clergy. Oftentimes when this fact is pointed out, the standard retort is that at least in schools there is no coverup or shuffling around of abusers. As we see from this report, that is a lie.
ALL such abuse is heinous and should not be tolerated in the least. But people should be more well informed and balanced in their opinions.
