All the more reason to keep your cell phone on record when going through the checkpoint.
And from what I have read, those states with 2 party agreement to record a conversation only applies if the conversation is private, a checkpoint is a public area and any conversation can be overheard so the conversation is not private. And the TSA allows recordings at the checkpoint except recording images on any monitors at the checkpoint.
Remember John Tyner, the “don’t touch my junk” guy and the campaigner for Ron Paul who had $4700. in cash with him, both had their cell phone recording their encounters with the TSA.
