From the affidavits...
On 06/19/2011 at approximately 1930 hours, I was dispatched to the Central Checkpoint of the Nashville Airport on a passenger refusing to pull up his pants. Upon arrival the suspects pants were down and his underwear exposed. He was given the oppurtunity to pull up his pants and refused, by crossing his arms after being directed. Small children were in the area during this time and passenger remained in this state until I pulled up his garments. Suspect was charged with the above.
