When Ponch and Jon pull over the roofing truck that has caught fire, Jon stops his motorcycle in front of the truck, and Ponch pulls up far behind the truck. Later, when they go back to their motorcycles, they are parked side by side.
When Ponch and Jon pull over a driver who turns out to be one of Jon's high-school classmates, the driver is wearing a glove on his left hand. This glove disappears and reappears throughout the scene, including in the middle of the person putting on his sunglasses.
The gun thug that shoots the police car goes from having a double barrel shotgun to a lever action rifle and then back to a double barrel shotgun.
In addition to the baby being born without blood or fluids or indeed an umbilical cord, it was the most pain free birth in history.
When Ponch calls in to ask for an additional cruiser and a tow truck for Baricza's shot-up cruiser, Ponch identifies himself correctly as "7-Mary-4," yet when the dispatcher responds, she calls him "7-Mary-3," which is Jon's handle, not Ponch's.
Baricza's police car is a '74-'76 Dodge Monaco that he pulls up in and radios that he will searching the grounds. As his car is about to be shot up, it is changed to a '72 Dodge Polara.
When Ponch and Jon are talking to teenagers who are supposedly law enforcement explorers, the uniforms the teens were wearing more closely resembled girl scout uniforms.
When responding to the bogus dirt bike call, the engine sounds from the 4 cylinder Kawasakis are those of two cylinder Harley Davidson motorcycles.
At the phony dirt bikes call, when the shooters are apprehended the film crew is reflected in Ponch's sunglasses.
When Ponch & Jon park and talk at the park, you can see the film crew and lights reflected in Jon's helmet.
After Ponch uses Baker's radio to call for a tow truck and the two of them gaze at the rear of Baricza's shot up police car, the tail light supposedly falls off of the car, but a crew member's reflection can be seen in the rear quarter panel pushing/pulling the tail light out.
Ponch and Jon would have known better than to go to the hospital to see the family. It would have been considered improper conduct as it could have been construed as an attempt to intimidate witnesses against them.
