"In each police station there is, apparently, a kind of scoreboard on which the convictions obtained by each officer are recorded. It is the number which counts, not the gravity of the offences concerned; and, as one of the ex-detectives at Wormwood Scrubs remarked to me, it is very much easier to arrest a homosexual than a burglar. A policeman whose score is lagging behind that of his colleagues can always catch up by going to the nearest public lavatory, or merely by smiling at someone in the street. By various promises, the arrested man can usually be persuade to plead guilty."
