What you'll accomplish
By the end of this guide, you'll be able to walk into court better prepared, in half the time it normally takes. You'll use ChatGPT to extract the key facts from an old incident report, identify the likely defense cross-examination angles, and build a quick mental outline for testimony — all from a phone or laptop the night before court.
What you'll need
CJIS Note — Important: ChatGPT is NOT CJIS-compliant. Before pasting any incident report text into ChatGPT:
Find the original incident report, arrest affidavit, or supplemental report for the case. This is what you'll be testifying about, so read it through once to refresh your memory.
Open a text document and type (or dictate) a summary of the key facts — replacing names and identifiers:
Original: "Officer Davis stopped John Smith at 4th and Main at 2300 hrs, case # 2024-04521..." Becomes: "This officer stopped the subject at 4th and Main at 2300 hrs..."
You don't need the full report — a 150-200 word summary of the key facts is enough.
I'm a patrol officer preparing for court testimony. I'm going to paste a summary of an incident. Help me: 1) identify the 5 most important facts I need to be clear on, 2) list likely cross-examination questions a defense attorney might ask, 3) flag any gaps or weak points in the narrative.
On the next line, paste your sanitized incident summary. Press Enter.
ChatGPT will return three things:
Ask ChatGPT to role-play the cross-examination:
Now act as the defense attorney and ask me these cross-examination questions one at a time. I'll answer each one, and you give me feedback on whether my answer is clear, responsive, and appropriate.
Go through 3-5 questions out loud — this builds the muscle memory for composure on the stand.
