"Despite its TSA-approved fold-out laptop sleeve, Luddite security personnel still insisted my tech had to be removed from the bag, but you can’t legislate against that."

In regards to a TSA-approved Messenger Bag. Not a surprise, really, considering the uselessness and confusion of the TSA.
One time, in an attempt to be proactive and efficient, I went up to a TSA agent and specifically asked if a yogurt cup I had would be allowed through security. His snide smirk and ‘what-do-you-think, quit-wasting-my-time-while-I-stand-here-and-chat-with-other-TSA-people really spoke highly of their attitudes and concerns regarding those flying. If I’m trying to get information, so as to be a better-informed flier, don’t be an asshat.
For those who want to start shrinking the size of so-called Big Government, I say start with the TSA.
