I was quite shocked by the idea that the secret service allowed this to happen. This is the story to me. I find it amazing that someone (inside) did not know them.

Based on what I have heard so far, you have two people who are not vetted in any way within arms length of international dignitaries, the VP, etc.

I would not think this could happen the way secret service reviews and practices procedure. They got lucky this was just a prank IMO.
