Every individual cannot be the final authority on the meaning of a particular clause because everyone won't agree.
so basicly words, not to mention the historical context, cannot be understood by the common man, so us common people need someone edgucated at a properly leftist school to learn us what terms like "congress shall make no law" and "shall not be infringed" mean?
For example
The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated,...Okay, so we know unreasonable searches aren't unconstitutional. That's the plain language.
But if you are the final authority on the meaning of that, I think I can guarantee that you'll probably never find a situation where the cops can come and search your house, and certainly never when you have something to hide.
