Per ABC News, "The director of national intelligence affirmed rather bluntly today that the U.S. intelligence community has authority to target American citizens for assassination if they present a direct terrorist threat . . ." (emphasis supplied; full story at the foregoing link).
To repeat: The U.S. government has arrogated to itself the right to deprive you of your life (let alone liberty or property) without due process of law, if an unidentified authority says they think you "present" a "terrorist" threat.
They are not talking about a situation in which you are actually, presently threatening anyone – e.g., if you were actually pointing a weapon at someone, or holding someone hostage – because in that case, they would have the right to kill you anyway.
No, they are talking about assassinating you ahead of time, because someone says they think you're planning something like that.
So, the entirety of the U.S. is apparently now a Constitution-free zone.
