Walker, Texas Ranger (1993)

In Harm's Way: Part 2 - S8-E1

Character mistake: Trivette hands the man in yellow a bullet recovered from the plane Walker and Alex were traveling on, which was shot down by an assassin flying a P-51 Mustang. This man, and later Trivette, mistakenly refer to the round as a "50mm," when in reality, Mustangs were equipped with M2 Browning .50 Caliber (12.7 mm) machine guns. (00:30:25)

Member of Terrorist Cell: You can't leave, we're at Defcon One.
Francis Gage: You guys really talk like that?

Question: Why is it the guys at the diner wanted Cahill and the teens out of there? What is up with them?
