@KateMoss1 I'm not sure who you are talking about, but I'll add more context to my reply. The most striking example of what protection just knowing the law doesn't afford you is this small spot of land in the Yellowstone National Park where theoretically no jury could be convened to put someone on trial, which has led the creation of a folk theory that you could get away with murder in this location.
Asked about it, a local attorney general just scoffed.
A slightly less striking example is the legal fiction "sovereign citizens" are living in across different countries. I'm not even sure they're wrong in their interpretation of their local constitution, but what I do know is that no judge would ever entertain their pet legal theories.
Knowing the relevant law only allows you not to give in to the aforementioned intimidation. Not sure what it gets you vis-à-vis politicians, they're just performing and it doesn't matter if their bluff is called out as they got to say their piece anyway.
