July 7, 2008, At Baltimore Washington International Airport this past Fourth of July weekend it was revealed that an individual was hiding a can of mace in his body cavity. While TSA did not actually discover the can, the placement of the can was so uncomfortable that the passenger left the security checkpoint for the nearest restroom.

The passenger ran barefoot because his shoes had already been sent through the X-ray when he abandoned the line. Law enforcement officers caught up with the individual after he left the bathroom and attempted to throw away the recovered can. The mace was confiscated and the man was allowed to rebook, but was later denied boarding when he again showed up at the checkpoint, this time with a bottle of lighter fluid in hand.
