The Weirdest Contraband The TSA Confiscated In 2016 So what’s the big deal if it’s inert? This inert 25mm round was discovered recently in a checked bag at Sonoma (STS). So what’s the big deal if it’s inert? First off, we don’t know it’s inert until explosives professionals take a closer look, and that takes time and slows down the line. It can even lead to a complete shutdown and evacuation. Anything resembling a bomb, mine, round or grenade is prohibited from both carry-on and checked bags. #TSAGoodCatch A photo posted by TSA (@tsa) on Jul 2, 2016 at 3:16pm PDT Pages: 1 2 3 4 5 6 7 8 9 10 11
