Sequence of necessary events for a government to introduce draconian legislation:
1) Make a press release (preferably on a Sunday, and even better on April Fool's day) that, whilst utterly devoid of hard fact, appears to announce a new law that is so extreme no-one can really believe it.
2) Allow press speculation and adverse comment to brew up into something hopefully near hysteria.
3) Reassure that everyone is indeed over-reacting - the law won't really be applied to them.
4) Press chums should now use the word 'backlash' letting those who want to live in a fools paradise resume so doing in the belief that the threat is being successfully repelled.
5) Sit tight while the fuss dies down, uttering soothing words only as necessary.
6) Wait for a suitable story in the press that can be twisted to illustrate just why the new law is needed and then choose that day to publish the proposed legislation couched in innocuous language, but containing more devil in the detail than was initially even suggested.
7) Deal with any hoo-ha that ensues by appearing to be all-ears to criticism. When everyone has practically exhausted themselves and are starting to get bored with the subject make just enough trivial concessions to shut up.
Bribe any remaining opponents with cushy jobs or blackmail them over expenses claims; ridicule the opposition for being weak on terrorism/paedophiles etc (whatever the mot du jour
9) Pass the legislation on a day everyone is heading off for a bank holiday weekend.
10) Don't make use of the new laws for a while in order to let everyone believe their fears were unfounded.
11) Take the now well-cooked frog out of the boiling water - and eat it, spitting out the bones.
