For readers who fly often, this blog from the Transportation Security Administration (TSA) can provide perspective, information, and, sometimes, entertainment. A great place to start is with the TSA Week in Review, a weekly post that reveals the number of firearms and other weapons or quasi-weapons TSA officers discovered in carry-on bags across the country. On the week of October 24, 2015, for instance, agents discovered 64 firearms. Of these, 54 were loaded, and 19 had a round chambered (that is, ready to fire). They also found two pounds of gun powder and 600 rounds of ammunition in a single checked bag, plus swords, knives, marijuana in a jar of peanut butter, and a host of other ill-advised luggage paraphernalia.
