The disrupting the screening process is a slippery slope. While I applaud the stance I think given TSAs lack of any real authority, any action that can be perceived as a disruption by a TSO and gives them cause to call in a LEO will probably not end well. I.e. I do not think it is worth while to provoke things that put the TSO on the offensive when they do have something to back them. However, putting them in the defensive is another matter. With either, it would behoove those that do, to do it in their home city rather than 1000 miles away.
