In the first crash, the white pickup with tar trailer is seen crashed when the yellow car is launched over the brown ramp car, then in the following scene we see it crash and the brown ramp car stop behind the trailer. Next, in the blue Oldsmobile with the white top, the woman driver is seen with both hands on the wheel, yet in the following scene the driver has their left arm out the window holding onto the roof. Finally, the location of the ramp vehicle changes from being uphill to being downhill.
The yellow Datsun Z-car with a black rear spoiler is seen behind Poncherello and Nelson when they respond to the first crash, and it is then seen stopped in traffic at the crash as they arrive. Additionally, the location of the crash has moved much farther away from the intersection than was shown when the vehicles were first seen crashing.
When Poncherello is fighting in the water, both Linahan and Bruce Nelson do not assist him and instead just watch from the beach. As trained and sworn officers, they would have instinctively helped him.
During an exhumation, the casket would be opened at the grave site, not in the presence of the next of kin.
Exposure to air cannot crack porcelain, otherwise all porcelain items such as dishes would be unusable.
All three officers pursue Woods. One of them would have checked behind the bookcase to see if Anna was there.
The first crash takes place close to a t-intersection near the end. The yellow car that rear-ends the ramp car could not have built up enough speed to do so after it turned onto the road.
As Poncherello and Bruce Nelson are leaving the report room after learning about the key, the wall to their left moves, as evidenced by the lights reflected in it changing position. This indicates the wall was a lightweight set piece, not real construction.
After visiting the amnesiac girl at the hospital, Bruce and Ponch are seen arriving back at headquarters, but it's yet another reuse of Ponch and Jon pulling in from an earlier season episode. The same yellow Volkswagen Bug and two Bell System phone vans are there, parked in the same spots.
When the casket is opened, the body inside is tanned flesh tone and the head is lifted at an angle, yet seconds later when the face cracks it is gray in color and laying flat in the casket.
The same blue 4 door Chevrolet sedan is used for both traffic incidents when the hearse is fleeing. It was also the first car to spin out in the first crash when Anna ran into the road.
In the first crash, the brown car is a ramp car that has a ramp installed on the rear section to launch cars that rear-end it. It can be seen many times throughout the series. Additionally, the cars in the crash are all unoccupied when the yellow car is launched and crashes, yet in the following scenes the occupants are seen getting out of them.
Once again, the same red Chevrolet Caprice Estate station wagon shows up, this time with Ponch and Bruce shortly before the crash with the amnesiac girl. It also shows up when they chase Tony in the stolen clunker car.
Poncherello tells Bruce Nelson they are assigned to Malibu for the rest of the week. The Malibu area is not within the CHP Southern Region which includes the Central station. It is in the Coastal Region so they would not be assigned to work there. Additionally, the officers were on the transition road from the S/B Harbor Freeway (I-110) to the E/B I-10. If they had been assigned to Malibu, they were going in the wrong direction.
When Ponch goes to handcuff Woods, he turns out to be an illusion with the real Woods driving off in his Cadillac hearse. There is no way for this to be possible since he was the one who opened the door for Ponch, Bobby, and Bruce. Before that, he had locked Anne and her mother up behind the bookcase. No actual illusion could do these things.
When Anna got into the car and realized it was not her mother, she could have easily opened the door and escaped.
In the hospital, the girl's flashback memories are from the point of view of whatever was chasing her. Her memory would have been what she saw, not what saw her, as it was later when she remembered her mother.
Bruce Nelson upon arrival at the first crash uses an incorrect 11-82 code (property damage) for the crash, and then fails to use the 11-41 code for fire and ambulance.
Elvira calls Central Station to tell Ponch that she has some news. Instead of just speaking to Ponch on the phone, she has him visit her at the comic-book store, yet what she tells him could have easily been relayed over the phone. It makes sense that Elvira might want to see Ponch and Bruce again, but Ponch shouldn't waste time and gas without even inquiring over the phone what Elvira knows.
