I fear Conor Gearty has it right in this article at comment is free today. He describes the process by which Conservatives throughout history have suddenly forgotten their proud liberal credentials upon being voted into office.
As Gearty writes:
The Conservatives have a long record of deploying state power to crush dissent to which their attacks on the poor and on organised labour have invariably given rise.
While I am happy to applaud their decision to drop the ludicrous and expensive ID card scheme, as Gearty says, there's no mention of repealing the Labour-introduced power to hold suspects for 28 days without charge. As he also points out, the one Tory who really cares about, and understands, civil liberties, David Davis, is nowhere to be seen in government.Dominic Greive, who should have been Home Secretary, but isn't, said in the Telegraph a couple of years ago, that 28 days is 'much longer' than it should be, and promised a review. It won't happen, and we can expect much more backtracking on civil liberties over the life of this government.
