To think this is an example of the real two tier policing:

Ex copper, woman at that, commits serious crime and funds a great lifestyle, when it comes to it she pisses off home and the men go to prison. Prisons that are awash with drugs by the way, because of shitbags like her.
So, IABU - two tier policing is either not a thing or is only about race
IANBU - two tier policing actually very often benefits white women and people in positions of power more than anyone else.
