Stupidity: With automatic weapons at the ready, doing a hit that takes less than 5 minutes (going by the hotel security footage), somehow one of the two robbers found time to give constant unnecessary update whatsapps to the guy in the car, with things like "Almost at the door" and"Keep the engine running" and "About to breach", all stuff that he didn't need at all for his job. Absolutely fantastic the "Meet you in garage" bit. To the getaway guy with his engine running in the garage. How logorrheic can you get? And those are trained Navy SEALs.
The Woman Who Never Died - S1-E3
Stupidity: The detective Magnum is with does not call reinforcements because they "might spook" the criminal, but he arrives on the scene making a lot of noise and with the emergency lights on. Even if the reinforcements arrived in police cars, they could have easily kept out of sight of the house and lurk around the block.
Stupidity: On his own in his helicopter, TC earlier in the episode spots a very hard to catch area of vegetation where supposedly the color of the leaves is different from what's expected. However for the ending, with 4 people in the helicopter, everyone but Magnum misses a giant clearing with a bright red excavator in the open.
First the Beatdown, Then the Blowback - S3-E4
Stupidity: At the end of the episode, Makani's skull is returned to the cave where it was originally buried. But it is left in a basket on top of some rocks at the entrance to the cave. It would seem to me that that is not going to be a very safe place, as anyone can see it. Should it not have been buried out of sight?
Stupidity: With one humongous stretch of luck (Magnum loses the guy he is looking for but TC who just happens to be generally 'in the air' is close for him enough to just be able to do air recon for him, and spot the guy who is still running because he must have gotten take-away food from half a city away on foot), Magnum arrives so close to him that they are in the same street maybe 10 meters apart. Yet Magnum needs another tip from TC and his passengers to spot him getting inside a house, something he could have never missed. (00:16:00)
