Built by a 23-year investigator

Practice the conversation before it counts.

Case File puts an officer in front of a person who answers back, remembers, asks questions of their own, and sometimes pushes back. Every run ends with a debrief that quotes the officer's own words.

This run she was: tired, slow to warm up; worked alongside officers for years; calm, normal pace.
What went right
Said why you were there"Somebody broke into the Pruitts' car overnight, so I'm checking with the neighbors."
Handled her questions"Nobody was hurt, thank God. I can't say much more yet."2 questions answered like a person
Kept it levelno threats, no pulling rank
Try next time
Not too many closed questions5 closed of 6. Swap a yes/no for a "tell me": "Tell me what you saw last night" gets more than "Did you see anything?"
The professional closeGive the case number, say what happens next, and how to reach you.
71%of the time, the officer's first 45 words predicted whether a traffic stop would escalate
3%of 161 recorded suspect interviews began with any rapport-building
418recorded interviews: even small lapses by the interviewer brought out the same in the person across the table, and less information

How a run works

1

Pick a door

Read the call, then knock. Who answers, and what mood they're in, is drawn fresh every time.

2

Talk

Say it the way you'd say it on the street. They answer back, ask their own questions, and react to how you treat them.

3

Read the debrief

What went right first, in your own words, then the two things to try next time. A score that grades the job, not just the manners.

What it is, and what it is not

What Case File is

  • Practice at the hardest skill in the job: talking to people
  • A debrief after every run, in the officer's own words
  • A record for the training file: runs, scores, certificates of completion
  • Any laptop, any shift, no room to schedule

What Case File is not

  • Not a lecture. You learn it by doing it.
  • Not a test with one right answer. Different people need different approaches.
  • Not built from anyone real. Every person, voice and face is synthetic; the city is fictional.
  • Not a replacement for your field training officers. It gives them more reps to coach from.
