From CHiPs Online:
When Kathy knocks on the woman's door looking for information on the drug dealer, she introduces Bruce as "Officer Nelson". Not yet, Kathy! He's still Cadet Nelson.
Ponch looks through binoculars at the guys breaking into cars. We see a typical binocular gobo. Anyone who has ever looked through a pair of binoculars knows that you see everything in a circle, not in that binocular view!
