I donno Mick. I'm starting to warm to the idea. Look what JB and GS are talking about; preemptive identification of the innocent IN CASE they commit a crime. Sure the up front costs are enormous. But think of all the work created! Not to mention all the work for lawyers and prosecutors clearing all the false positives!

What's say that you and I start a consulting company and bring this about in private industry. We get specially built ass scanners that can simulate the output of every commercial photocopier known to man. For a generous fee we build a data base of scanned asses of all people entering and leaving public and private buildings then use specially created butt matching software to match asses. Armed with this technology, we would be able to, with a high degree of certainty, almost instantly catch any employee or visitor who dared to photocopy his or her own ass and post it on a company bulletin board.
