Under what condition do individuals have REP in the whole of their movements, even in public?

• A. When the government tracks for 7 days or more
• B. Only when inside a home
• C. When wearing a tracking device
• D. When there is a warrant

Answer: (A)

The key idea is that privacy in a person’s movements grows with the scope and duration of surveillance. When the government tracks where you go for an extended period, it collects a detailed map of your daily life. That level of detail reveals intimate routines, associations, and choices, making one’s movements a private portrait even though many locations are in public view. A longer tracking period makes this privacy interest strong enough to be protected as REP in the whole of your movements, and such pervasive surveillance is generally treated as a search that requires proper authorization.

Seven days of continuous tracking is used here as the threshold because it turns routine, public movements into a comprehensive record of behavior. The other options don’t match this idea: being tracked inside a home is private by default but doesn’t address public movements over time; merely wearing a tracking device is surveillance but doesn’t by itself establish REP in all movements; and having a warrant is about legal authorization, not the condition that creates REP.
