Body-worn cameras have become one of the most important tools in modern policing — not just for transparency, but for investigations, evidence collection, and courtroom testimony.

On this episode of Forensics Talks, I’ll be speaking with Bryan Chiles, Senior Manager of Axon Forensics, about how Axon body cameras are helping shape the future of law enforcement. Bryan has been with the company since 2005 and has played a key role in developing and testing both TASERs and body-worn cameras. Today, he serves as an expert witness in cases involving Axon technologies and works closely with legal and forensic teams around the world.

We’ll talk about how Axon cameras handle authentication, SHA256 hashing, chain of custody, automatic activation, and more — and why these technical features matter when it comes to reconstructing events, reviewing use of force, and building solid cases.

In this episode of Forensics Talks, we're tuning in to the science of sound with Henry Vega, Forensic Engineer at JS Forensics Consulting.

Henry will walk us through how dashcam audio recordings can be used to calculate vehicle speed, how tire frequencies are analyzed in real-world crash cases, and how firearm discharges captured on officer bodycams are helping uncover key evidence. We'll also explore his collaborations with experts around the world pushing the boundaries of audio-based forensic reconstruction.

If you’ve ever wondered how much information is hidden in a sound file — this is the episode for you.
