A computer could monitor the whole lot, no problem.
No it couldn't. At some point, as I said earlier, a human must make a decision. There are not enough humans alive (and never will be) to monitor all communications in this country (or monitor all CCTVs etc). It's pure paranoia
Anyway, all you've said there is just another way of saying "If you have nothing to hide, you have nothing to fear" - so we'd better all hope there'll never be any proper cunts in charge of deciding what is 'something to hide'.
I'm saying that it is, always has been, and always will be, physically impossible for the government to do what the paranoids believe will be the result of "Big Brother" initiatives. Big Brother initiatives can
only target and intrude into the lives of people already targeted by the authorities for whatever reason. Take CCTV for example, how many hours worth are recorded every second? Probably a year's supply in the click of a finger. Nobody can or will view all of that just to see what random people are getting up to. However, the authorities
will retrospectively view recorded footage
if they are looking for specific information on a specific individual. Emails are no different. Even if they did record everything that was written by you or me in an email (which despite what the paranoids and the smug self fart sniffers believe, isn't true), the only time anyone will ever read it is if we do something to make us a target (ie are suspected of a crime).
It's not a case of "if you have nothing to hide you've nothing to fear" (which, incidentally, is a perfectly logical argument), because these initiatives probably won't help detect whatever it is you're hiding in the first place.
"Big Brother" initiatives are purely for retrospectively targeting known individuals, it isn't intended to find out what everybody is up to in their spare time, nor would it be possible for them to use these initiatives as such.
