And even knowing and admitting they cannot predict the future behavior of their agents, they still exempt them from the same security screening they require of everyone else in secure areas of airports. This is proof that their cattle screening policy is not about keeping us safe. It's about getting us used to having our 4th Amendment rights violated. As Mo McGowan, a former Assistant TSA Administrator publicly said, "No one likes to have their 4th Amendment violated, but we're going to have to do it anyway."
