Once, they brought the explosives unit — several armed men — because of sticker residue on the back of my computer. Another time, they brought a team of dogs to search me. Once, they took my crying 2-year-old through the screening process by himself because he clung to my husband during a pat-down search. Recently, they took me to a private room and forced me to open my pants and show them my underwear. They hid their badges when I asked for their names.
