What do you take from the "sources" comment in the WTimes that he "saw it coming?" If the Chileans were adamant that they were providing the security, and the SS breached their prerogative - should we be happy, mad, sad, pi$$ed at the Chileans or pi$$ed at the Secret Service for anticipating this altercation and not informing the President of the threat?
Teh Chileans were trying to "stick it to us", putting our President in danger, for power play.
Sounds like he was informed......his grep-and-grok elapsed time was approximately zero.
