Thats a good one, however there are those who believe that we should not say anything, even if we do find a human head in a bag because we are not there to specifically look for human heads. Plus the prescence of human heads is not a threat to airline security as long as we do not allow the guy to take his machette on board as well so that he might add to his "collection." ...LOL The rationale eludes me.
