Land of Black Gold: Part 1 - S2-E10
Plot hole: Thomson and Thompson fall asleep whilst driving their jeep and are arrested because whilst they were asleep, they drove into and damaged several people's markets and as well as driving into the wall of a building. Although the decision to arrest them would seem normal due to the vandalism, it does not make sense why both of the detectives would have gotten arrested. Even if they both fell asleep at the wheel, only one of the detectives was actually responsible for the vandalism caused by this. (00:19:00)
Chosen answer: If Hector was seriously intent on removing King Ottokar's scepter from the glass cage holding it and launching it through the window with the camera, then Hector would have been forced to knock out the two guards so they would not have interfered with Hector's plan as soon as he removed the scepter from the glass. As for Hector, himself, was explained when Tintin was explaining how Hector stole the scepter. Tintin placed a twig inside the camera and it launched out of the camera. Hector would have placed the scepter inside of the camera, and would have been knocked unconscious due to the spring effect created when the scepter had been launched.
