How come most of the criminals are half-naked? :D
Apparently, many European police forces have adopted the Stalinist Russian method used by the NKVD and MGB/KGB to arrest people between the hours of near midnight to 3-4 in the morning. Where they are least likely to be prepared for defense/escape, and where they will be lesser of a problem to deal with since it's the period of their REM sleep and half their brain is asleep while they still put the cuffs on them. Also while many of these middle aged men are wearing their "half-naked" PJ's. Completely unfair on the criminals part....but it works.
