I think that this handover is designed to allow for the operation of these drones in American skies in a "more legal" manner. It is well known that the CIA is not SUPPOSED to operate domestically. But since 9/11 the US military has increasingly ignored Posse Comitatus. With this handover the federal government will have a quasi legal means of commiting drone strikes domestically. It will happen. I promise you that it's coming. But before that thee drones will be used for more illegal domestic surveillance.
