I think Rivero raises an interesting question and I still can't think of an answer beyond the obvious.
They allowed Bush to sit, reading about a pet goat, at a time and location that had been public knowledge for weeks prior to the attack! Are they just incompetent? Stupid? Or were they privy to information that allowed them to be CERTAIN he was not a target?
Any ideas? Am I missing something?
"How did the United States Secret Service Protective Detail know they did not need to immediately move the President? How did they know they did not need to toss him into his bomb-proof limo and start driving in any direction to foil a possible inbound?"
"How did the United States Secret Service Protective Detail know that by leaving the President where he was, they were not making targets of all those students and teachers?"
"How did the United States Secret Service Protective Detail KNOW FOR A FACT THAT PRESIDENT BUSH WAS NOT A TARGET THAT DAY?"
