We already know that the NSA has access to information specifically requested by an individual either by showing probable cause if they are a U.S. citizen or using some other specific request if they aren't. It doesn't seem likely a low level border agent would have access to this. If this is standard operating procedure, don't you think we would have heard about it from other people who were presented with printouts of their facebook messages when arriving at the border? Or more likely, this is FUD that leaves out specific facts (border agents don't have broad access to facebook messages) to give the impression it is linked to a big trending news story.
