I can't speak for coppers in the Met as they seem to have a totally different set of rules and ways of policing than anywhere else in the country. What strikes me as odd is that if the account is true the copper involved didn't have to stop the two fellas he could have excerised his own discretion and decided not to stop them if he had wanted, sounds like a cop out (pardon the pun) on his part to suggest that he was simply following orders, I'd say that was bollocks. Unfortunately, discretion in todays police seems to be used less and less, I tutor new PCs and the impression I get from them is that they are so terrified of making a mistake or being complained about that they are afraid to excercise discretion and would rather go by the book or stick to a decision once they have made it. I tell them time and again that it is the single most important skill in their possession and to change your decision or admit you got it wrong is the hardest thing to try and get coppers to learn!
Stop and search is a vital tool for police in detecting and preventing crime but it must be used correctly and reasonably. maybe the copper concerned in the stop of the two black guys could have done it differently. Perhaps he could have engaged them in a general conversation first without it becoming an official 'stop', made conversation about their night out and if they had managed to get some good photos. Maybe then he might have realised they were not a threat and were just ordinary fellas out and about and they could have parted ways amiably without incident. Certainly that approach would work in Brighton but this is London we are talking about and perhaps the official stop approach is much more prevalent given the history of events up there.
Blah blah - cop talk.........full of shit - all of you - imo.
