They don’t mess around at Camp David, and they don’t like Obama being there.
Obama hates the place because of the intense scrutiny upon each and every person there every single minute, thus Obama takes a big risk being there if he has to communicate with his handlers, sends a courier out for some blow or having a conference with his caddy.
This also shows a deviation of Obamas routine, why indeed would he be there? A security issue? Internet chatter?
Does he feel paranoid enough and distrustful of anyone with a weapon from the SS to any police officer of the Park Service he has to run off somewhere like a political ostrich, hiding in the sand until it cools off?
Certainly, with communications in question, power down except backup, AC on the fritz, utilities in question and the huge constant surveilance subject to glitches, am sure he feels threatned. He knows he is not popular and people do stupid things when the system is broken.
