Another professor showed me a large paper of instructions for discovering plots and conspiracies against the government. He advised great statesmen to examine into the diet of all suspected persons; their times of eating; upon which side they lay in bed; with which hand they wipe their posteriors; take a strict view of their excrements, and, from the colour, the odour, the taste, the consistence, the crudeness or maturity of digestion, form a judgment of their thoughts and designs; because men are never so serious, thoughtful, and intent, as when they are at stool, which he found by frequent experiment; for, in such conjunctures, when he used, merely as a trial, to consider which was the best way of murdering the king, his ordure would have a tincture of green; but quite different, when he thought only of raising an insurrection, or burning the metropolis.
Which reminded me of a lot of posts on Security Theater and profiling in the aviation industry which I read on Schneiers blog recently, however, it reminded me the most on the report of the development of a new technology which registers wether someone on board of a plane is a terrorist by watching how they act. Maybe they should put technology in the toilets instead ;). I really like how a 300-year old satire still is so uptodate.
