##  [Field Interview Report](/field-interview-report-0) 

 Definition

An investigative concept defining processes used to identify facts, preserve information, and support lawful adjudication outcomes. It governs planning, collection, documentation, and verification of information through structured investigative steps and records. It does not justify unlawful collection methods and requires integrity controls to prevent contamination, loss, or misattribution. It materially affects case solvability and prosecutorial viability by shaping reliability and completeness of the record. The concept is generally stable, though methods and technical standards evolve with forensic and digital capabilities over time.



 

 

 

 

 

 





## Principle

Principle

Capture contemporaneous, concise facts and leads from voluntary or investigatory stops to preserve memory, establish a record of suspicious activity or community contacts, and support later investigative or intelligence development while respecting civil liberties.

 

 

 

 

 





## Demonstration

Demonstration

An officer approaches a person seen frequently near recent burglary locations, documents the person's statements about whereabouts, identifiers such as tattoos and vehicle description, the time and place of the contact, and notes to refer the information to detectives for pattern analysis.

 

 

 

 

## Misapplication

Misapplication

Treating a field interview report as equivalent to probable cause for arrest or using it to record coerced or fabricated statements; conversely, failing to document legitimate voluntary contacts that later prove relevant.

 

 

 

 

 





## Consequence

Consequence

Properly used, FI reports create a searchable record of low-level contacts that can link patterns, corroborate witnesses, identify suspects, and inform resource allocation without converting noncustodial encounters into arrests improperly.

 

 

 

 

## Reversal

Reversal

If every field contact were treated as the start of a formal arrest or booking record, routine community engagement and intelligence-gathering would be chilled and administrative burden would rise.

 

 

 

 

 





## Boundary

Boundary

Intended for noncustodial contacts and preliminary observations; it should not contain formal charges, substitute for sworn affidavits, or record custodial arrests—those belong in arrest or booking reports.

 

 

 

 

 





## Semantic Tension

Semantic Tension

Tension exists between preserving broad intelligence (subjective observations, community tips) and ensuring admissible, corroborated fact; FI reports must be factual and avoid investigative leaps presented as fact.

 

 

 

 

 





## Synthesis

Synthesis

A field interview report is a concise, factual record of a noncustodial investigative contact that preserves immediate observations and potential leads for later investigative or analytical use while maintaining appropriate procedural limits.
