Sent the link with a quick message to ask the TSA about this in March to Chaffetz's Twitter. As we might have guess, he's not a happy camper and would like to speak to the person who filmed this or the family videoed. Sent a message via YouTube to the poster. Hope he or she will contact him.
Frankly, after seeing this and reading the description, I think I'm done with public transportation. They are at my local bus stop, the Greyhound station, the train station, the Metro. And now they are searching AFTER travel? Yep, I'm officially done.
Off to write even more letters to my unresponsive reps...
