Party Crashers

The news is loaded with stories about the White House party crashers. I'm listening to Glenn Beck pontificate that White House security is so tight that no one could just crash the party, it must have been an inside job.
Sorry Glenn, no security is that tight. Show up at the right time, dressed right, looking like you belong, have some paperwork, doesn't have to be the right paperwork, anything will do. You will probably get in.
Back during the Cold War we used to keep nuclear armed aircraft on alert. We took this seriously, and had pretty decent security on the flight line. Everyone had badges, we had a fence, armed guards on the gate, the whole nine yards. But, every time we had a security inspection some thing would get written up.
There was this colonel on the inspection team who had a trick security badge. It looked OK except instead of his picture on the badge, there was a picture of his dog. That bastard always managed to fake out some gullible security guard with the fake badge. The colonel looked like a colonel, was dressed right, and his paperwork was almost in order. That was enough to get him thru the gate and get us a writeup for a security violation.
I think you crash a White House party the same way. You look right, you dress right, and your paperwork is almost in order.
