This is true.
There have been thefts of dvds in one of our libraries, and the security people set a trap with the cctv cameras and caught the guy. The police were called. The thief said 'I'm going to be in so much trouble' as it isn't the first time he has been caught.
The police said to him he had two options.
one - he could confess, it would take about an hour and they would give him a life home.
two - he could not confess, they would have to go to a major police station in the city about 12 miles away, and they wouldn't give him a lift home.
In the light of such brutality - ie having to get home on the train or the bus instead of getting a lift in a nice police car - he decided to confess.
