We've seen a number of stories involving TSA agents being arrested for any number of crimes. Everything from assault, to child pornography, to murder. This shouldn't be a surprise at all. Which is not to say that all TSA agents ARE the scum that they tend to be made out to be. But it's a worrying program.
In terms of this kind of activities detailed in this story... well hell. I know from talking with a former TSA employee that this sort of thing is VERY common. I've even meet a former TSA agent that not only admits doing this at an airport in California. But he did it aallll the time. And he wasn't the only one doing it.
