There was an item on TVOne news tonight about the (expensive) liquids and gels that they have to take off people at airport security (yeah, slow news night).
Why do they confiscate these items? Because passengers may be hiding explosives in them.
So then why, in the last part of the news video, do they have all these items displayed on an open table in an open office, in front of Karen and Sharon? If the items are dangerous they should be in a safe and secure area, and if they are not dangerous, then... then the passengers should be able to take them with them (like in the old days!)
