After reading this I concede the argument to you. Certainly with the released articles you can see how easily one could be confused against the truth. I quoted the NY Times and was mislead.

That link was pretty good, that undercover cop captured the mood of things there, it was actually quite pleasant and friendly, the Washingtonians were nice and even the cops came to relax and start to see things as pretty good duty.
Something interesting about this thread is that most of these posters are not interested in learning about the massive thousands of active duty combat units, the arrest of 13,000 Americans, or hearing about internment camps to house them.
Those are the points of information that I thought was relevant to this thread.
