On his show today, TB was trying to make the point that eyewitness testimony is the least reliable (an assertion that is correct.)

But he did so using what he depicted as a first day "criminology class" event used in many criminology courses.

TB claimed that a criminology teacher will ask the class if anyone "has a gun" and if no one raises their hand then he will signal a plant to carry out the "experiment."

at sometime during the class, a person bursts into the room and starts firing a gun at the teacher. the gun is "loaded with blanks." The teacher falls to the floor as if shot, and after the assailant leaves the room, he gets up and informs the class it was a fake staged event. then he asks the class to describe the assailant to prove how faulty their observation skills are under stress.

TB's idiotic scenario fails to take into account that most people who are legally armed wouldn't let anyone know. Even if asked by a college teacher.

someone who is legally armed might feel in danger from the situation, draw their weapon, and fire a "non-blank" and the actor, causing a justified tragedy.

TB needs to think these things through better.
