TSA messed up again. But it's the congress that is really at fault.
They authorized TSA and Homeland security and fund them every year. Until we can articulate why TSA must be dissolved, our liberties will keep disappearing. First planes and then trains. Next it will be cars and then warrantless searches of our homes, unless we send congress a clear message to get rid of the TSA.
You can definitely get rid of TSA with enough pressure on Congress, but you'll never get rid of the screening they do.
