Sounds like a basic summary is the rules are not consistently applied across the U.S. and that the actions of TSA screeners aren't always in line with the regulations that appear on the TSA web site.

I wonder if anyone has tried printing out a copy of the regulations from the web site and shown them to a screener when they conflict?

Not that I expect it to help. It really seems that if you want to actually get on the plane you need to shut up, keep your head down, and do whatever the TSA says.

It's a British firm, clearly the secret ingredient is tea! ;-)
