As a teenager I was stopped on a few occasions usually on my way home from pubs in Camberwell, Peckham, etc. It was par for the course, the boys in blue thought lads of 18 , 19 were obviously up to no good. Having said that, I wouldn't want their job, it seems no matter what they do they are on a hiding to nothing. They seem to get accused either of being inactive and useless or heavy handed.
