It will now be interesting to see the result of the internal enquiry.
My guess, he will be found "Guilty" of unprofessional conduct and dismissed the force.
As far as I am aware, the only evidence that showed he may have done anything wrong was the CCTV clip when the woman was being manhandled back into the cell after she ran out causing mayhem. She knew she was there because she had refused a blood test.
The CCTV clip showed her falling to the floor and everyone assumed that the policeman had pushed her down. I was never sure about that as his arm followed her rather than looked like it was actually pushing down.
We now know that the woman had been holding onto the door-frame to resist being put back in the cell after dropping to the floor so that she had to be dragged (which was all her own fault). When she let go of the door frame, she sprang down to the floor and this is what we saw.
As far as I am concerned the woman is a clear case of silly bitch gone stroppy and now spinning to the media out of control.
The original argument at home was probably about her own drinking and then she ran out to drive off in the car. I bet she was way too drunk to drive and pulled over after half a mile and promptly fell asleep.
Very silly silly woman.
