Re: People. The person you need to write to is your MP. @John Smith 19
Sadly when I chose to write to my MP about this when it was still being debated, his reply consisted of a large think envelope containing all the forms that have to be filled out when undertaking surveillance.
Of course this ignores the way in which the various services effectively self-authorise what they do making this whole thing a monumental waste of time but he didn't seem to be interested in hearing that.
Too many MPs are blindly following the government and have done so repeatedly in the past. For them to change course now would involve the acceptance that they had previously made mistakes, and most people should know how difficult it is to get an MP to actually do that.
