Law

People pass the strangest laws, laws that can very easily be abused: In the UK, they now have the religious vilification law and the 28-day suspension of habeas corpus; in Canada, they can lock you up for "advocating genocide" or some such thing; in the US, we have RICO. When these things are being proposed and people object, the advocates always say that their law could be abused, in theory, but in practice it won't be.

Well, that's like saying that if you throw somebody out of an airplane, in practice he'll always land on a trampoline.
