No email professing love? No emails expressing displease with the government which then mean you end up getting moved from your house (as gerrymandering has been used in the past)? No email joking about a drunken night out? No email to a friend moaning about someone at work? No email to a family member explaining that a medical test came back positive/negative? No dodgy email sent to you by another person? No porn sent to you by a spam email? No email sent to you by a friend in confidentiality? I presume that you have net curtains on your windows to stop people looking in to see what you are doing? Why do this when you have nothing to hide? One question comes down to this, do you trust this *and all other future* governments not to misuse or lose the information? There are good mathematical reasons why this large-scale collection of data is worthless, and there are good ethical reasons as well. I wouldn't mind this data being collected if it were due to a Judge's warrant, but to cast this wide of a net is both ineffectual and I would suggest illegal - against the Human Rights Act and your right to a private life. And remember - you are paying the government to spy on you - because YOU might be a naughty person. I know I don't.
