Falconer’s Law:

I propose a new law, to be called Falconer's Law. It states:
"as a political discussion progresses the probability of reference to an absolute and unchanging measure of good behaviour approaches 1. When this happens the discussion must be terminated and whoever alluded to this fictional concept of absolute goodness has automatically lost whatever debate was in progress."

The law is named after the English Lord Chancellor who deployed the technique in a Channel 4 documentary (Dispatches: Stealing Freedom). In essence his message was “if you are good you have nothing to fear from the government.” How scary was that?
