Other mistake: Magnum spots a patrol car inside the impound lot. He and TC duck down, and they are at the side of the car. The same side the camera is at, when it gives us a view of the patrol car passing by. It's plain daylight, and they officers have to be completely blind to Miss those two big dudes lying by the side of the car in a spot they have a clean eyesight on. (00:36:20)
Other mistake: The whole Ferrari/pick-up truck shenanigans of this episode conveniently forget Higgins having usage of a perfectly good Mercedes. (00:47:00)
Other mistake: A plastic bag with a wallet and a watch, placed right next to a claymore mine when it explodes with a whole car, would hardly stay perfectly intact, and completely untouched by the police when they already towed the car to the impound lot.
Other mistake: This episode is the season 2 finale, but was obviously produced early, with numerous shots from it appearing in the opening. A big deal is made out of Magnum borrowing "the Rolls Royce of cameras", but he has used routinely the camera throughout the season. Higgins even asks him if he needs instructions about the various lenses, when one of the previous episodes involved as sub-plot replacing one of the priciest ones, and the feature-length episode had a bit about it as well.
