So their argument is....
We want you to have no privacy, so we can protect you by arresting/fining people after they've invaded your privacy

Smart thinking that .. do they really think we're that stupid ? .. I don't understand why they even bother trying to justify it, just be straight and say "this is NOT about privacy, we don't give a **** about your privacy, it's about surveillance".
They're happy to chuck your privacy/security under the bus to make their life easier .. problem is
it doesn't work, the goal is to satisfy their paranoia by being able to surveil at will, but
all it does is feed their paranoia.
