Ron, you never answered.
Please explain how your actions as a TSA passenger- and bag-searcher would be different than they are now if you "went looking for" tennis balls (instead of "going looking for" WEI), but still contacted a supervisor when you found things that looked like weapons, explosives, incendiaries, drugs, pictures of naked 17.5-year-olds, stolen credit cards, fraudulent passports, or evidence of immigrations violations. Wouldn't your actions be exactly the same, regardless of whether you purported to go looking for tennis balls or for weapons, explosives, and incendiaries? If so, of what significance is the fact that you went looking for tennis balls, went looking for WEI, or went looking for nothing at all?
