U.S. Transportation Department officials said that registration is a critical step in the persecution of UAS operators who violate the law. Responding to media questions during an Oct. 19 press conference, Transportation Secretary Anthony Foxx explained that law enforcement officials in many cases can easily secure an offending drone, but often have trouble tracing it back to its operator on the ground. Registration would be both a tool for law enforcement and a deterrent to potential crimes. "The important thing we are doing today is establishing what the rules are," added FAA Administrator Michael Huerta. "And the rules are—we expect you to be registered if you operate within the NAS. With that clarification, which is an authority that we currently have, then that creates a template. If you are not operating with that proper registration, that provides a basis for us to go after you and with our other law enforcement partners."
