She got three years because she was convicted on two charges, so got a year for one and two for the other. The judge’s sentencing remarks indicate why he was ‘harsh’ with the length - she forced the victim to give evidence and showed no remorse for her actions.
I really think the sister and mother should have faced charges too. It’s pretty clear that the mother sent her the photos to use on the escort site and knew and encouraged what she was doing.
And the sister?! What a fucking coward (amongst other unpleasant aspects to her personality). Presumably SHE didn’t post the pictures up because she knew how illegal it was and knew there’d be a threat to her job.
She must have come into contact with victims of sexually abusive crimes at some point in her police work, and would certainly have had training on the impact etc, but chose to egg her sister on. She’s no loss to policing, but the CPS should have had her up in court with her sister. Arguably, SHE should have faced the heavier sanctions, because of all of the above.
