Mr Cameron also said that a Tory Government would pass a new law to ensure that the intelligence agencies would be able to track phone calls and internet messages.
He said that this power to track “who made which call, to which person, and when” was “absolutely crucial not just in terrorism but finding missing people, murder investigations, almost every single serious crime.
“What matters is that we can access this communications data whether people are using fixed phones, mobile phones or more modern ways of communicating via the internet.”
I refuse to believe our PM is so technologically ignorant that he believes the 'banning encryption' policy will ever fly. The most plausible explanation to me seems to be that he is trying to rebalance the public's expectations of privacy towards greater surveillance to the extent that slightly less egregious (but still objectionable) laws can be passed in their place. I have a feeling that this kind of rhetoric has been used before and probably has a name.
