Absolutely agree this is disgraceful and shows that the govt. and cops think they can get away with police state behaviour. NO ONE has marched into parliament to search MPs or arrest them for doing their jobs since Charles I, FFS, when this country was an absolute monarchy.
But let's not forget the Tories have done this kind of thing too - poor Sarah Tisdall went to prison for leaking info as a civil servant and Clive Ponting only escaped chokey by the skin of his teeth. It was dreadfully wrong then and it is dreadfully wrong now.
What the Thatcher government didn't have was quite such an apparatus to bring in a police state (although they came pretty close as anyone who lived in mining areas during the strike can testify).
Thatch didn't have a DNA register, didn't have 3,000 new offences, didn't have the Regulation of Investigatory Powers Act, didn't have the sort of anti-terror legislation there is now.
She didn't reverse the basis of government keeping personal details - used to be they couldn't share info between depts, now they are obliged to share. Used to be the case personal info could only be used for the purpose for which it was given, now that's been turned on it's head as far as the government is concerned.
My godmother's late husband was an eminent historian. He warned me we'd have fascism back in this country within three decades of the 90s. Certainly any less "benign" government would have all the apparatus in place ready to get cracking the minute they marched into power.
