I propose we start a petition. It would read something like this.
In a lifetime all British Subjects can kill 1/1000th of a human being without any recourse from the law. So we wouldn't have Politicians who get up everyone's knows, Giles Brandreth, Matthew Parris, or (And here's the advantage, No SBGG!) So long as you can get 999 other people to agree with you.
Of course members of the House of Lords would be exempt, rank hath its privilege.
