We are going in circles here as we have gone through these points in the previous pages - but since you commented:
I have Dr Duff's truthful testimony of her unlawful arrest and brutal treatment.
You have the piece that was in the paper/social media. But you don't have her interview record which will have been under caution and submitted to the court. This is what the court will have used. You also don't have the statements & other evidence provided by the CPS. And as you don't have either, you can not make a judgement as to what actually happened on the street which led to the arrest.
I know that the police officers she encountered were misogynistic, corrupt, unprofessional liars.
How do you know if the officer who arrested her was involved in any other part of what happened to her? Its quite common for the arresting officer to hand the arrest over to someone else to book them into custody and giver the circumstances & necessity for the arrest. The arresting officer plays no further part.
I know she was acquitted and her honesty commended at the trial.
And did the court make any reference for the 'dishonesty' of the arresting officers? And as you don't know what actually happened prior to and during the arrest - you can not justifiably say that So if Dr Duff told the truth, and the court certainly believe she did, then the officers must be lying.
I know the Met had to apologise for the disgusting behaviour of its officers in Dr Duff's case.
I am not disagreeing with you - in fact i have repeatedly said that the language used and the comments made were wrong and if the process which i described on page 6/7 for searching was stepped outside of and she was assaulted for no reason other than to effect the search - then it was wrong..."
Going forward then......
You are correct, police should not arrest women, men or people of any age, gender etc to punish them (much to the displeasure of families with unruly kids who constantly ask us 'can't you just keep him in the cells for the night to teach him a lesson?'). No, the answer is no and always will be.
And - if this was the case with Dr Duff - baring in mind I wasn't there at the arrest either - then this would be clearly wrong.
But if other things start to play into the incident - can you see that it starts to get complicated?
So, the youth who was searched and was found with a knife - can we agree that he shouldn't have this and he commits the offence of possession of bladed article? And as such an arrest may be lawful.
So - if that youth is under the police's control (ie arrested) we can't have people passing 'things' to him as we don't know what it is. It might look like a business/advice card - but it may be adapted to be a weapon or have drugs on it etc etc. If that person then becomes 'agitated' with not being able to pass this card (and bare in mind neither of us were there so we don't know how it played out) it may lead onto obstructing police or assault police?
The police can not fast forward time to see if she is going to found not guilty at trial either.
So how would you prefer to see cases such as assaults on police dealt with? Are you happy for the police to arrest in such cases and bring them into custody?
And in custody, who would you want making the decisions for things such as strip searching? And what would be the logistics in that - ie what would happen to the person whilst they wait a decision?
