One of "Rumsfeld's rules" is:
"Hire paranoid, they may have a false alarm rate, but they discover all the plots". It was originally said by Herman Kahn.
When we are at war and it comes to the safety of President Bush, being paranoid is healthy.
I agree that this was NOT a safe situation for the President. I have already said that. Trust, but verify, I'm all for that.
I'm just saying that the plans were in place long ago. IF we agreed to them, we should have followed them. If they were unacceptable because of a risk to the President, then:
1) We should have demanded, 6 months ago, and obtained an exception that would at least allow one or two S.S. agents to go through the main entrance with the President, while the rest of the detail would have already been in position inside to meet him. [Now, perhaps this exception WAS agreed upon, and the Chilenos screwed up and forgot. That is possible.]
2) If the Chilenos would not allow an exception, then the President should not have attended.
