Note that this is NOT supposed to be the way it works. But if you get a screener who takes that attitude, chances are you're stuck with it. Supes all-too-often back the screener regardless of whether or not they're correct, and getting a LEO involved is rarely going to work out well (and here, LEO will probably say he/she has no say over the way screening is conducted and may threaten to arrest you).
