I'm sorry to say mate but the little scumbag who has confessed to nicking lots of cars has only done so because of the f*cked up legal system in this country which means the more cars he owns up to the more police files can be closed the less time (if any) the F*cker spends in jail!
It happened to me a couple of years ago, i got a phone call out of the blue from the coppers about a car of that mine which had been broken into and the tw@t had owned up, it restored some of my faith in the police force untill i told my mum (who works in a Young Offenders institution) and she told me about it usually if they get caught doing one they will admit to a load more to get their sentance cut
