What is the effect of government tracking for 7 days or more on REP?

• A. It gives REP in the whole of a person's movements, even in public
• B. It gives REP only in private spaces
• C. It has no effect
• D. It requires a warrant to be valid

Answer: (A)

Long-term location tracking by the government fundamentally changes how privacy is protected. When tracking runs for seven days or more, it reveals a detailed, continuous picture of where a person goes, when they go there, and with whom they might interact. That level of detail about daily life is highly privacy‑sensitive, so a person develops a reasonable expectation of privacy in their movements even in public spaces. In other words, sustained tracking crosses a line where the government’s collection of location data becomes a search under the Fourth Amendment, and it generally requires a warrant supported by probable cause. This is the idea behind why extended location data is treated as implicating REP, reflecting how modern surveillance can intrusion into areas people reasonably expect to keep private.
