I was channel surfing the other day and happened to stop on C-Span.  The video was at the Cato institute and featured speakers from PapersPlease.org and the other from Epic.org. The topic was how much the TSA knows about you and your movements about the globe. Things they shouldn’t know, they know. It was a very revealing talk. I suggest you watch at least the first 15 minutes of this video. I watched most of it and was astounded. I’ve included the link below.
