R.I.P. Scout26
8. Unusually bulky, loose-fitting apparel worn in hot weather. In countries like Israel where security is paramount, officers are trained to spot people whose clothing seems out of place or disproportionate to their body type. Increasingly, that's a concern U.S. officials are talking about as well, because thick or baggy clothing can be used to conceal weapons. Could someone sporting a large sweatshirt, vest, or jacket on a blazing day be suffering from a head cold or just be fashion-challenged? Of course. Sure. According to SecureTransit.org, seeing something out of place like that is also a reason to take notice.
