This has been the thing that always confuses me about the TSA. They create bottle necks that essentially concentrate people to a small area. Forget a major airport like LAX or LaGuardia, medium sized airports have more people in those lines than on a flight. If the threat level was anywhere above basically nil this would have to change. Plus if you want to get in it's easier to fly a small plane in. All I can think is that TSA in its current form has caused more danger than it has prevented. It's security theater if red team almost always wins.
