Homeland Security USA: There Could be a Tiger in There

En route to Cuba, an airline passenger experiences a different kind of heat when she's detained at Miami International Airport and suspected of carrying large sums of undeclared cash. Meanwhile in Laredo, Texas, agents wonder if a bus traveler from Mexico has more in mind than home repair when he enters the U.S. with four cabinet doors. Sixteen high-spirited young women cross the Ambassador Bridge from Canada and say they're heading to Detroit for a bachelorette party and officers at the border try to make sure they're up to nothing more than fun and games. Skagway, Alaska may be the "loneliest" U.S. crossing, but for the husband-and-wife agents at this border crossing with Canada, minimal traffic still means maximum diligence.
