This is the second time Officer Baricza draws his gun. The first was in the episode "Peaks and Valleys" (season 2, episode 1) in response to two villains shooting holes in his patrol car.
At 5 minutes in Ponch radios to Jon that the "suspect is G. O. A." GOA means "Gone On Arrival (of the police officer at the scene).
This is the only time when one of the "CHiPs" officers draws his weapon. It wasn't Ponch or Jon, it was Baricza after he had been beaten up by Billy.
