Raul, David, and Javier immigrated to the United States from Colima, Mexico, to find jobs and help their families. When they learned that a mutual friend, Francisco, planned to travel to Colima, they asked him to deliver various sums, totaling more than $25,000, to their families. During customs inspections at the border, Francisco told U.S. customs officials that he was not carrying more than $10,000, when in fact, he carried more than $35,000. The government seized the cash and arrested Francisco. Raul, David, and Javier requested the government to return their cash, arguing that Francisco was a gratuitous bailee and that they still retained title. Are they right? Explain fully.
