I met a guy recently, lovely bloke, really friendly and welcoming - knew everybody. We were working in the day and then went for a drink and he started giving me all this stuff. "Did you know that police use what's called legal language and if you say you understand the charges then you're essentially pleading guilty? And I've got police mates and even they don't know about it, it's so secret, but that's what they are doing?" "If you get a birth certificate for your child then you've actually consented to them being governed by all of these laws? Same with the census, there are questions in there that are coded and if you answer them then you're agreeing you can be arrested. Parliament can't make laws, they can only make Acts of Parliament and if you don't consent to them then they don't apply to you..." etc etc.
It was weird cos he seemed like a really sound bloke up until that precise moment.
