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.
