Are you looking for a big government research grant?
Just wondering.
Not particularly. However, we do need to get a handle on this problem. As things are now, it is like “acceptable losses” on the battlefield. Which is an unacceptable attitude.
Of the screening that might be used, none will ever be particularly certain; so it would be unfair to not let teachers teach because they might, possibly, someday molest one of their students.
Instead the attitude should be one of mutual protection. First and foremost protecting students, but also protecting teachers from false accusations, and protecting the school and school district from liability.
The alternatives are intensive and intrusive surveillance, which stinks, sentencing teacher who do have sex with their students to draconian prison sentences, etc. It is just better that the opportunity for such things is avoided in the first place.
