Law Enforcement Officers Planted a Tracking Beeper on the Clothing

Law enforcement officers planted a tracking beeper on the clothing of an individual in order to track the individual from one location to another. Shortly thereafter, the individual traveled home where the movements of the person within the residence were tracked. How is this police activity most likely to be viewed by the courts?

A) Constitutional because the U.S. Supreme Court has ruled that a tracking device does not invade a person's privacy.
B) Constitutional because the tracking device was originally planted at a location other than the private residence of the individual.
C) Unconstitutional because the in-home movements of the individual were not generally open to visual surveillance.
D) Unconstitutional because tracker devices cannot be used in any context.
