In the USA protection against Tyranny is fragile.

  Some thing to keep in mind, devastating economic collapse is one of the events that can lead to the misuse of and or destruction of the mechanisms there to protect society from tyranny, then giving reign to tyranny.  There is talk of the mechanisms in place to prevent tyranny from happening in modern US society.  9/11, in reality, was a much smaller event than a economic collapse.  It brought about the chipping away at the Bill of Rights (some provisions of Patriot Act, NDAA, FISA), Ben Franklin ”Those Who Sacrifice Liberty For Security Deserve Neither.”  The last 20 years have been an assault on the “Bill of Rights”.  See provisions of: NDAA, Foreign Intelligence Surveillance Act (FISA), Patriot Act, Anti-Terrorism and Effective Death Penalty Act of 1996
