Which scenario best illustrates probable cause for arrest or a search?

• A. An officer observes a person standing near a closed door in a public park.
• B. A person appears nervous during a routine traffic stop.
• C. A reliable informant states that the person is selling drugs at a known location, with corroborating surveillance.
• D. An anonymous tip claiming a crime happened nearby.

Answer: (C)

Probable cause means there are specific facts and circumstances that would lead a reasonable person to believe a crime is being committed and that the person before you is involved. In this scenario, a reliable informant reporting drug sales at a known location, plus corroborating surveillance, provides detailed, trustworthy information and independent confirmation. That combination makes the officer confident that illegal activity is taking place and that the person is involved, which satisfies the level of belief needed to justify an arrest or a search. The other situations don’t meet that standard. Simply seeing someone near a closed door in a park doesn’t show illegal activity or involvement. Being nervous during a routine traffic stop might raise suspicion, but it isn’t enough on its own to justify arrest or a search. An anonymous tip could be persuasive if it’s highly reliable and corroborated, but without corroboration, it generally doesn’t rise to probable cause.
