What is a 'FI' and how is it used in radio operations?

• A. A field interview; a non-arrest encounter where information is gathered; radio updates may be needed for report.
• B. A formal inquiry with court involvement.
• C. A field investigation that ends in arrest.
• D. A federal inquiry.

Answer: (A)

Field Interview is a non-arrest contact with a person in the field to gather information about possible suspicious activity. In radio operations, officers use this to communicate with dispatch and other units what they’re doing, who they’re talking to, and what information is being collected, so everyone stays informed and records can be made for a report if needed. The purpose is to verify details, check for warrants or known involvement, and document observations without detaining or arresting anyone. This differs from a formal inquiry that would lead to court involvement, or a field investigation that ends in an arrest, and it isn’t a federal inquiry.
