"You should also realise that because there are so many people out there, and so few security people to watch you..."
That argument might have carried water 30 years ago, but not today. With things like face-recognition software, behavioural-analysis software and the massive storage capabilities of today's computers, you don't need "security people" to watch you - the software does all that for them. Effectively, you ARE being watched all the time, and the moment you do or say something that the ruling elite don't like, that software will flag you up and turn you in within a heartbeat.
