I am asking you to exercise your common sense. If you do that, I think you will have to agree that the President is safer with agents protecting his front and his rear when he is entering an area such as a room. Given that, I really don't care what the Chileans say or what any other leaders agreed to. Those other people aren't the President of the United States, which means that, whatever the Chileans are saying, they were way out of line - a fact which is perhaps best demonstrated by what the President ended up having to do vis-a-vis the Chilean police.
Ummm...I'm all about common sense, and I've posted it several times. I don't need to repeat myself.
