Why do I think you're being willfully obtuse, here? What you're proposing would require nothing short of a constitutional convention, and what we end up with on the other side of that process may not actually be the America we grew up in anymore.
How does a law that limits the government ruin America? Or specifically, how does a law limiting the use of surveillance footage by police ruin America? Why would it require a constitutional amendment? I honestly don't understand your reaction.
To be clear, I am only talking about laws that limit the gov't.
Because the process I mentioned is the only feasible way to create "a law that limits the government", especially given the current legislative climate, and that process is incredibly dangerous.
