Character mistake: Higgins is extremely protective of any little trinket and bric-à-brac at the Estate, but in this episode he barely bats an eyelid at a post-impressionist masterpiece being handled casually, rolled up and passed around. He handles it pretty badly himself.

Other mistake: Magnum gets inside the Waikiki Natatorium War Memorial climbing athletically over the closed gate. The bad guy comes roughly from the same direction, but given his physical state, one wonders how could he accomplish such a feat - it is conveniently kept off camera, but he comes from a direction with no gates. To beat him to the finish, Rick picks another direction entirely just walking around the bleachers! And they all end up at the same location.
