Over the past couple of months, I've been following for my job a trend in airport security. Basically, this job pays so low that they're having difficulty filling it. The ones who run the X-Rays start at $5.75 an hour. Plus, when you can't get people to work, you get understaffed security checkpoints, and tired, overworked overtime workers.

I talked, as part of my job, to the top HR executive at the company that provides airport security to the majority of U.S. airports. He told me that the number one employer that they lose airport security personnel to... is McDonalds. They pay more.

So in short, the people checking for weapons in the airports are the ones who are not qualified to work at McDonalds.

Now, there is a possibility that this was all done from the inside. Nevertheless, that security weakness still existed. I was waiting for it to be exploited, fearfully, but I had no idea that it would be exploited so effectively.
