How can the credibility of a informant be established for probable cause?

• A. Demonstrating past reliability, being a citizen informant, statements against interest, and independent corroboration
• B. By the informant's identity alone
• C. By the officer's opinion
• D. Without any corroboration

Answer: (A)

Credibility of an informant for probable cause rests on indicia that the information you’re relying on is trustworthy. The strongest foundation comes from a combination of factors that show the informant is reliable and the information is hunch-free. Demonstrating past reliability means tips that have been confirmed in the past are consistent with what’s later found, which signals that the informant’s future information may also be trustworthy. If the informant is a citizen, not a confidential or paid source, that status often suggests a real, independent concern for accuracy rather than pressure to produce results. Statements against the informant’s own interest are important too—when an informant risks self-incrimination or other consequences by sharing information that could be false, it adds credibility because lying would be costly. Finally, independent corroboration by other, separate evidence or observations strengthens the tip by showing there is more than the informant’s word to rely on. Relying on the informant’s identity alone does not establish credibility, and an officer’s mere opinion about reliability lacks the objective support needed. Proceeding without corroboration leaves too much room for error or deception, so corroboration is typically required to transform an informant tip into probable cause.
