Maybe you should get a criminal ticket... with little "punch out" dots... for every citizen.
One free burglary, one free rape, one free car theft, one free assault and one free "general" category crime (criminal's choice).
You know, everyone gets a "get out of jail free" card, like in Monopoly.
When all the dots are punched out, then the little scamp has to go to Jail for two weeks or something and also gets a STERN warning not to misbehave again.
Of course, you COULD do the reverse "transportation" idea. All the decent, law-abiding Englishmen can leave and move to some pretty island with nice beaches and leave old Blighty to your criminal element.
That would solve the problem too, I guess.
