Who exactly is teaching police that people carrying small copies of the Bill of Rights are potential terrorist suspects? Also, what exactly is the result of this teaching. Are those people treated differently? Same questions for the paying-with-cash thing. I buy lots of stuff with cash, yet no LEO has suspected me of being a potential terrorists.
ETA as for the Founding Fathers being terrorists, when I look at the Boston Tea Party I see a textbook example of terrorism.
The U.S. Code of Federal Regulations defines terrorism as "the unlawful use of force and violence against persons or property to intimidate or coerce a government, the civilian population, or any segment thereof, in furtherance of political or social objectives" (28 C.F.R. Section 0.85).
I am not prepared to say all the Founding Fathers were terrorists, but I am not prepared to say that none of them were terrorists. I am willing to reconsider my position if presented with additional evidence.
