AI for criminal defense lawyers, without trusting it blindly.
How can criminal defense lawyers use AI?
AI helps defense lawyers most with volume: hours of body cam audio and stacks of discovery. A good tool turns them into a searchable transcript and a list of facts, points out places worth a second look, and ties everything to a timestamp or a page. It never decides what the evidence means. That stays with you.
Where does AI help a defense practice?
The time in a defense case goes to reviewing evidence. That is where AI earns its place.
| Job | What AI does | What stays human |
|---|---|---|
| Body cam and dash cam | Turns hours of audio into a timestamped transcript you can search, and points out places where the same person says two different things. | Watching the moments that matter. The recording is still the evidence. |
| Discovery | Reads reports, statements and scanned pages, and lists the facts with the exact words and, for PDFs, the page they came from. | Deciding what is true, what is missing, and what to challenge. |
| Timeline | Puts every dated fact from the file in order, so gaps and conflicts stand out. | The theory of the case. |
| The charges | Lines facts up against each element of each charge, for and against. | Every strategic call, and anything that goes to a court. |
| Research and drafting | General AI tools can draft and summarize quickly. | Checking every citation. Courts have sanctioned lawyers for filing cases an AI made up. |
Why body cam review is the best first use
A single traffic stop can come with hours of footage from several officers, and someone has to sit through all of it. Most of it is nothing. The few minutes that matter are easy to miss at hour four.
That is the job AI does well: listen to all of it, write down every word with its timestamp, and flag the places where a story changes. The lawyer then watches the ten minutes that matter instead of the six hours that do not.
What should you demand from any AI tool?
Five questions to put to any vendor before a client file goes in. We hold ourselves to the same list.
- 1
It tells you where it heard it
Every line of a transcript should carry its timestamp, and every fact from discovery its page. You should be one click from the source.
- 2
It tells you what it could not hear
Wind, sirens and radio chatter wipe out words. A good tool shows which stretches produced no words at all, instead of skipping past them.
- 3
It does not draw legal conclusions
It can tell you an officer said two different things. What that means for the case is the lawyer's call, and a tool that pretends otherwise is a risk.
- 4
You control where the evidence goes
Discovery can come with a protective order that limits who may see it. Know exactly where footage and files are processed before you load them.
- 5
It is honest about what it misses
Automatic transcription mishears words and mixes up speakers. Treat it as a map of where to look, not a substitute for the recording.
What we built for defense lawyers
We built our body cam tool because a criminal defense firm asked for it. It is live there today.
- Bodycam Reader is a Mac and Windows app. It transcribes the footage on your own computer, so the video is never uploaded, then gives you a searchable, timestamped transcript, flagged inconsistencies, and a coverage view that shows where the audio produced no words.
- You can ask it questions about the recording, and it answers only from that transcript.
- Our case-file reader lists every fact in discovery with the exact words and, for PDFs, the page it came from, and tells you which files it did not read. Lining those facts up against each element of each charge is rolling out now.
How we hold our own reader to account is in our AI document review guide, and the rules we suggest for any firm are in our AI policy template.
Common questions
Can AI watch body cam footage?
The useful tools today listen, they do not watch. They transcribe the audio, search it and flag places worth a second look. You still watch those moments yourself.
Is it ethical for a defense lawyer to use AI?
Yes, if you treat it like any other tool that touches client files. ABA Formal Opinion 512 applies the existing rules: understand what the tool does, keep client information confidential, tell the client when its use matters to them, and bill honestly for the time. Many state bars have added their own guidance, so check yours too.
Is an AI transcript court-ready?
No. Treat it as a finding aid that shows you where to look. If a transcript is going to court, it needs to be checked against the recording like any other.
Does the footage have to leave our office?
Not with every tool. Some run on your own computer so the footage is never uploaded. Ask every vendor this question before anything else.
