I beg your pardon, Rosie if I have got something wrong re off duty police officers, but I did say 'except in an emergency". You use the expression 'when something goes down' which I take to mean some kind of emergency, but an empty-handed woman walking along would surely not have been any kind of emergency.
Sorry winterwhite I did type a longish reply to you that has disappeared into the ether. I'll try again. No of course Sarah Everard was not an emergency. Couzens had no business even talking to her, let alone arresting her. He is a despicable man who went looking for a victim and found poor Sarah. He abused his position and brought shame on his profession.
I didn't explain myself well. When my son started his Met training he was told he was never 'off duty'. One example he was given was that if he was out socially in a pub for instance. If a fight broke out and he didn't intervene and police were called and identified him as police (met had to always carry their warrant card) then he could be on a disciplinary. Not a situation that most of us would regard as an emergency.
I admit I get upset when there's blanket condemnation of the police (not you I hasten to add), not improved because my son was beaten quite badly while on duty and the offender only got a 'telling off' from the judge. Nobody knows better than good police like my son what the rotten apples do, and he wants them out as much as anyone. It's up to the senior ranks to act on the reports given to them by other officers. Sadly they can be slow to do so.
