Tonight after work our friend decided to go to a yoga class at the Dupont WSC.  Our friend walked into class and sat down next to one of the RWers (big mistake, her words).  There were no cameras at that point.  The cameras arrived as the class was about to start.  They stayed for awhile at the beginning then left and came back.  No one in the class was asked to sign a release and our friend was told that the teacher would and that would be enough [Editor's note: what?!]  She said that none of them could say where they were from or why they had cameras following them and one was wearing stripped pajama bottoms that looked ridiculous.  My friend described them as annoying and whiny (shocker).
