More consistent inconsistency ... My Northwest: TSA confiscates shampoo, but not a gun in Bellingham The Transportation Security Administration routinely confiscates shampoo and hand sanitizer, but not guns. A TSA screener discovered a revolver in a man's carry-on bag at Bellingham International Airport this week. The .22-caliber Derringer handgun was loaded with five rounds of ammunition in the chamber. After some questioning, the man was allowed to turn the gun over to a friend, who wasn't getting on the plane. He then boarded the flight, which was delayed by the investigation.
