> I rather live in a world where the police or CPS chase every frivolous compliant than them unable to do anything without a court order or not stopping abuse enough.

There is a middle ground between "unnecessarily destroying people's lives over frivolous complaints" and "not doing anything without a court order". The term "not stopping abuse enough" is too vague to speak to. There is no system where no family will be hurt unnecessarily, and no system where abuse is completely prevented. The goal is to minimize both.
