This problem with them is Australia wide not just QLD, My friend tells me the police are sick of the way that some of them behave.
Locally in Sydney there was a case that brewed for a while where a Lawyer was accused of Child Abuse. He lost his Practice, He Lost his Children but at a later day it was proven in court that Dchs in NSW lied and framed the guy, yes this also made interesting readings in he paper and he is now suing the state Government for millions and so he should.
