And your list of allegations points out another problem.

I can understand insulating police officers to some extent from criminal charges incurred in the line of duty while the court process is taking place, because the nature of their job is going to mean that they get hit with more than the average number of charges for things like assault that end up not panning out . . . but there's no way intimate partner violence should be occurring in the line of duty for police, and they should not be protected from it. (Given extra mental health supports in a bid to avoid it, sure, but once it happens they need to be treated like everyone else.)
