Ok,, then. Let's say I'm a career criminal. I started doing burglaries when I was a nipper and worked my way up through Twoccing, ABH and crossing borders with drugs up my bum to become Britain's leading armed robber.
Call it ignorance, call it complacency, but one day I become careless, and leave my dabs at the scene of a crime. At 5am the next day I am woken by a commotion outside my house. I open my curtains to see wall-to-wall plod outside, waiting to nick me. Being the quick-thinking chap that I am, however, I open the window and shout "Too late, boys, I've retired!"
That'd work, wouldn't it?
