When I exercise my fifth amendment right to silence when I am questioned upon attempting to re-enter my home country, I get arrested and harassed and threatened for hours and hours.
The phones are all tapped, the cops rule everything, and all of the basic rights we were told we had are now exercised only at the mercy of the military rulers.
A few years ago I went back to the US to visit the crypto museum (incidentally, right across the street from NSA in Fort Meade). It was my first trip to the DC area and the first night I got in, I went over to the Jefferson memorial. A sign on the pathway approaching the dome warns visitors that due to federal law, firearms are prohibited on the grounds.
Jefferson would be proud, I'm sure.
[note to non-US citizens: It's basic right #2 in the USA that people can own and carry firearms.]
