A Cessna single-engine plane conducted nearly 58 hours of surveillance, more than 38 of them over Buffalo. In Minneapolis, the call came from an agent in Homeland Security Investigations, the branch of Immigration and Customs Enforcement that conducts longer-term investigations into terrorists, weapons trafficking and drug smuggling. Air and Marine Operations, which also dispatches drones from Sierra Vista, Ariz., and Corpus Christi, Texas, was not able to send the aircraft until the next day. After about two hours of surveilling, the agent and other law enforcement agencies said it was no longer needed. Air and Marine Operations officials said agency protocol prevents infringement on the right to protest.
