Bomb threats may be made in letters or notes, delivered either personally or through the mail system. Packages intended to mimic or represent bombs, including backpacks, luggage, bags, or attache cases, even if they may not have the capability of exploding because of poor construction or intentional choices, are still treated as potential explosives, as in the case of 13 devices mailed to various politicians and opponents of Donald Trump.
