Tracking people over terrain: What's real, what's fiction?

Tracking people over terrain: What's real, what's fiction?

Author: Zachary Elwood October 26, 2025 Duration: 50:34
Have you ever wondered how tracking people actually works? You’ve probably seen a lot of Hollywood depictions of how law enforcement track people over external terrain, and maybe you’ve wondered what’s real and what’s exaggerated. I talk with Rob Speiden, an instructor in what’s called “sign cutting." Rob breaks down real search-and-rescue, law-enforcement, and military use-cases; why “broken twigs” and deep foot prints are actually weak evidence; how pros actually determine the age of sign using weather history and side-by-side comparisons; and why disciplined interviewing at the start of a mission can save hours later. He’s blunt about the limits of tracking, too—like why you can’t easily deduce someone’s weight from track depth alone. Learn more about your ad choices. Visit megaphone.fm/adchoices
