Nothing to fear
IIRC it was David Blunkett as Home Secretary who said that everyone's PCs should be open to random searches by the police. He also said that anyone buying a child an ice cream should be investigated. He even used the immortal words "If you are innocent you have nothing to fear from a police investigation",
Another politician at the time said "David Blunkett wants everyone in jail who isn't David Blunkett.".
Most Home Secretaries seem to go totalitarian when they are appointed. The only exception that springs to mind was Roy Jenkins. Unfortunately he set the expectation for us first time voters that the 1970s would herald a golden age of personal liberty. Politicians have been a disappointment ever since.
