The truth is much more complicated and involves politics. For example Seattle (and possibly other cities?) enacted a law that involves paying damages for being wrong in the event of bringing certain types of charges. But that has resulted in some widely publicized examples where the prosecutor erred by being overly cautious.

There needs to be consequences for shitty, procedure-ignoring police work. Period.

Minimum 1 year of jail time for grossly wrongful arrests that could be avoided with standard procedure or investigation tactics that were not applied.

I would absolutely never call the police on a woman. Simply walk far away and let her be someone else's problem.
