We are policed by consent, which is indicated when a copper reads you your rights OR asks you 'do you understand?'
Understand is synonymous with 'stand under'. So when they say do you 'understand' by replying 'yes' you are standing under 'their' rules.
By stating 'NO' I do not consent to 'your search' 'this arrest' 'the taking of DNA''Blood samples' or 'to be placed on any database' you then put them under strict oath, which is that unless you are committing a breach of the peace, committing harm or loss to an individual, they then have to stand under the oath they swore at their attestation to uphold common law, not statutes, not legislation, and certainly not what they have fabricated on the spot.
But the initial question was about the TV licence, its not against the law, it may well be against legislation, but is certainly not breaking the law.
A little like smoking on public transport, buses ect. it's not against the law, which is what all the signs state, it IS against legislation, and if you are caught then it will be legislation that they attempt to force on you first, then once they get Joinder (you confirming your name 'mr' mrs' miss' etc ) they are then able to use that legislation against you, because you have given it the force of law because you consented and we are governed.
Does that make sense??
