Officers need not reveal the true reason for a stop as long as what exists?

• A. The suspect consents
• B. The stop is lengthy
• C. There is probable cause to arrest
• D. Reasonable suspicion exists

Answer: (D)

The main idea is that a brief detainment or stop is legally justified when there is reasonable suspicion—specific, articulable facts that criminal activity is afoot. If those facts exist, an officer can stop and question a person even if the exact motivation or true reason isn’t disclosed to the public. The rule focuses on objective evidence, not the officer’s inner thoughts, so a stop remains lawful as long as reasonable suspicion exists.

Consent would also allow detainment, but it’s not the standard required for legality. A stop based on probable cause to arrest would authorize an arrest, which is a higher standard than needed for a brief stop. Therefore, the best answer is: reasonable suspicion exists.
