It turns out that civil liberties aren't the only thing being trampled in Tony Blair's zeal to pass draconian new anti-terrorism legislation: his government is also trampling on British constitutional convention by involving the police in politics:
Before the vote, chief constables were asked by Charles Clarke, the Home Secretary, to lobby individual MPs in an effort to win backing for the controversial detention plans. However, it has emerged that top-ranking officers made vehement objections to the police being used to act as "political messengers" for the Government.
And so they should have done. It is quite improper for any public servant to be asked to lobby Parliament on behalf of the government - they are supposed to be politically neutral servants, not advocates for the government of the day. And that especially applies to the police; the only worse people they could have asked to act as their messengers would be the intelligence services or the military.
