A citizen informer can be distinguished from the typical informant in that officers should attempt to obtain what from the informant to assess reliability?

• A. The basis of the informant's information
• B. The informant's name
• C. The informant's past criminal history
• D. The informant's address

Answer: (A)

Assessing reliability hinges on understanding how the informant arrived at the information. Knowing the basis of what they are reporting—whether they witnessed it themselves, learned it from direct observation, or heard it from others—directly reveals the likelihood that the information is accurate and trustworthy. If the informant can explain the origin of the facts and provide details that support them, investigators can weigh the report more effectively and seek corroboration where needed.

Details like the informant’s name, address, or even past criminal history don’t tell you how solid the information is. They help with identification or context about the source, but they don’t illuminate how the information was obtained or its credibility. The basis of the informant’s information is what matters for reliability because it shows whether the information comes from firsthand observation, well-supported sources, or mere rumor, guiding how much weight to give it.
