In the following fact scenario, identify if Private Citizen would have a reasonable expectation of privacy. Support your position by citing relevant caselaw, holdings, and/or tests.

1. Private Citizen is sitting outside in his enclosed backyard talking to his friend who is the local drug dealer. A drone operated by a private investigator flies overhead remotely recording a video of Private Citizen in his backyard.
2. Would your analysis change if the drone remotely recorded audio conversations in addition to visual images? Why or why not?
3. What result if the drone was operated by local law enforcement and remotely recorded both audio and visual images?
