Even if the APS had a policy on handling incidents of employee pedophilia

Principals and other administrators are not really required to follow it.

Wherever there is written a policy that seems to be binding; one also finds at least a tacit weasel clause.

Sometime not so tacit. The most candid example is included in the student behavior handbook. The document seems binding; in particular the part entitled minimum mandatory consequences for student misconduct, except for the inclusion of the following statement in the beginning of the handbook;

"Nothing in the following is intended to prevent a ... principal or other administrator from using his/her best judgment with respect to a particular situation."

So in any "particular situation", a principal or administrator does not have to follow policy; and can use their own best judgment on how to proceed; even with employees who are pedophiles.

Best judgment does not require explanation or defense;
it is what it is; best judgment.
There is no review process.


And there you have it, in a nutshell.
