"Nelson said even if McGann truly is innocent and didn't intend to harm anyone, he still thinks that McGann showed "a lack of good judgment" and "was not being very smart" in traveling with the watch."
This. To me this was a raising brow thing when I read the article. Either is this ingnorance of the current rules, or was a publicity stunt.
I know the rules, I follow them, thus never had any issues in airports. But there is a golden rule: if you feel like you are probably going to break a rule ( by carring somethin g strange, for example), do the first step. Always. And it works. Heck, I moved a a few bottles of finest lager from Munich to NY, I went to AA representative and after explained she agreed with me taking them.
