On May 3, U.S. Homeland Security agents at the Fort Lauderdale, Florida, airport detained three young activists returning from their first trip to Cuba. The three were released four hours later with just enough time to catch their connecting flight to Los Angeles. In a violation of constitutional rights, the agents took the travelers’ phones and presumably inspected them. The cops offered no reason for the detentions. A handful of other people returning from Cuba were also detained at the Miami and Newark airports, so the Florida detentions were not an isolated incident.
