So, I'm sitting on the tram this morning on the way to work. The tram stops and a mob of plainclothes ticket inspectors flood in through every door and start flashing their badges and politely asking all passengers for their electronic tickets. These are held up against a sort of Tricorder clutched in the hand of each inspector which informs them whether the passenger deducted their fare when boarding the tram.
One or two irregularities are detected and the inspectors cluster around the embarrassed offenders and electronically lock-in their penalties.
I look forward to the day when the inspectors will flash a badge and take hold of any eReaders being used by passengers, run them past their little Tricorders and seize anyone unfortunate enough to have a pirated or DRM-broken book in their storage and escort them into waiting busses.
There's no reason to limit this to public transport, the inspectors could go into cafes and parks, as well, into any public spaces where people read. And they could check phones as well as eReaders. Or even USB sticks.
It will be a great and wonderful day for the Law!
