Free for All - S1-E4
Continuity mistake: Throughout the episode, Number 6's lapels switch from having solid to broken white piping and back again.
Continuity mistake: David and Kathy exit to the outside of the building, closing the inside door and the outer door. When Sheriff Carver exits to the outside, the inner door is not closed, but open as he steps out.
Visible crew/equipment: As Joe approaches the third car with the bad guy in it, there is an unknown man, possibly a crew member, reflected in the back window where there wasn't a man before.
Factual error: The chopper's main rotors are at a speed enough to cause rotor wash, but the men's coats or hair don't move at all, when they should have been buffeted around.
