Which Fourth Amendment exception allows seizure of evidence observed in plain view?

• A. Consent
• B. Plain view
• C. Exigent circumstances
• D. Stop-and-frisk

Answer: (B)

The basic idea is the plain view doctrine. A seizure without a warrant is allowed when the officer is lawfully present at the location, sees incriminating evidence in plain view, and can tell immediately that it is evidence of a crime or contraband. The key is that the observation must be accidental in the sense of not requiring the officer to move things or search to recognize it, and there must be probable cause based on what is plainly seen. So, if an officer is legally where they are (not trespassing or acting on a warrantless overstep), spots something clearly incriminating without manipulating the scene, and knows right away what it is, they may seize it without a warrant. This is what makes the plain view doctrine the correct choice. Consent would require a voluntary permission to search or seize. Exigent circumstances would justify a warrantless action only because of an urgent emergency or risk to evidence or safety. Stop-and-frisk covers a brief stop and pat-down based on reasonable suspicion of danger. None of those hinge on observing something in plain view and seizing it immediately; they rely on different justifications.
