Other mistake: Magnum is shown in Captain Greene's office in uniform. He is wearing a US Navy Parachuteist Badge, his SEAL trident, and has the rank of Lieutenant. In the show intro section, he is always shown wearing just the trident, and has the rank of Lieutenant Commander. Was he demoted? (00:03:15)
Factual error: A taxi pulls up to a private jet at an airport in Hawaii. A public taxi cannot just pull up to an aircraft at an airport. It needs clearance to access airside areas. (00:21:05)
Factual error: Continuing the crossover with Hawaii Five-0, the CIA is supposedly searching people's homes, holding hostages, threatening to kill them if an SD card is not produced. This is not what the CIA does. They gather intelligence overseas, not domestically. And they are not a law enforcement agency. The FBI handles matter within the US.

Continuity mistake: Magnum and TC are in a stairway. TC points a security camera up so it does not cover a landing. Magnum and TC exchange a conversation, and the next time the camera is shown, it is pointing at the landing again. (00:12:55)

Revealing mistake: Mr. Castro is feeding Ellie the Goat an apple. If a goat were to be biting an apple, the cuts would be irregular. But a few moments later the apple is shown and it has two cuts and they are straight - both made with a knife. (00:25:30)

Plot hole: TC is being held at gunpoint and is told to get in a car in the parking garage and drive. Magnum cannot get a hold of TC on the phone and says that something is wrong. When TC drives off with a gun at his head we see Magnum in the Ferrari, in the parking garage and in pursuit of the car TC is driving. How did Magnum know that TC was being held at gunpoint and that he was in a car in the garage? (00:38:25)

Visible crew/equipment: Magnum and TC are hurrying to catch an elevator in the parking garage. As they approach the elevator, you can see a cameraman against the wall on the right side that should not be there. The next shot shows the scene from that cameraman's perspective. (00:39:30)

Plot hole: In an effort to keep Glenn's death as quiet as possible, Higgins hires a private pathologist to do an autopsy to see if there were any foreign substances or poisons in his system when he died. A few scenes later it is revealed that Glen was undergoing chemotherapy. How is it possible that the pathologist missed the cancer and the chemo treatment in his investigation? What he found was an excess of antacids.
