Final answer:
Drone owners must register their drone regardless of age. The Fourth Amendment protects against unreasonable searches, but its application to drone surveillance is still evolving.
Step-by-step explanation:
According to current regulations in the United States, drone owners must register their drone with the Federal Aviation Authority (FAA) if their drone weighs more than 0.55 pounds (or 250 grams). Age is not a factor in the registration process.
As the use of drones raises privacy concerns, the Fourth Amendment of the U.S. Constitution is potentially relevant. The Fourth Amendment protects against unreasonable searches and seizures and requires a warrant for searches, including into someone's home.
However, the Fourth Amendment was originally written in an era when surveillance methods were limited. Today, with the increasing capabilities of drones, questions have been raised about how the Fourth Amendment applies to drone surveillance and the boundaries of privacy.
