Detective Barr

Detective Barr appears as one of the local law enforcement figures the FBI's Behavioral Science team encounters while investigating cases in the field. He carries the skepticism and procedural caution of a working cop confronted with unfamiliar new methods, more comfortable with hard evidence than psychological theory.

Todd Faulkner plays him with the flat, unimpressed authority of a career officer who has seen federal agents come and go. The character works as friction — a grounded, procedural counterweight to Holden's theorizing, reminding the show that not everyone is sold on profiling yet.
