Other mistake: The human trafficker Sang Min covers his retreat from the warehouse firing wildly with a Micro Galil. In the time it takes for Steve to shout to the others if anybody is hurt, he somehow already ran all the way to his Mercedes deep up the alley and start it up so it can make a nice screeching noise and ram McGarrett. (00:34:50)
Continuity mistake: During the undercover operation, Danny tells Chin to pull the plug on the operation "Let's get her out of there." Steve's hand is on his belt, but it then cuts to a close-up where he has his hand on the radio. Similarly, during a cut to a close-up on Daniel Dae Kim, Scott Caan's arm pops up in view out of nowhere. (00:32:35)
Continuity mistake: The police operation with Kono undercover begins showing a timestamp on the video feed saying that it's "Monday, 21:16:40" (approx). Inside the warehouse though, when the smuggler boss asks her what she does for a living, we're back in time at 21:14:18. From then on, the time changes inconsistently to 21:15:33, 21:16:46 (more than a minute when she is just turning around), 21:16:04 (again wrong order) and as he sends a text to the mole, the reply comes at 9:24, which would mean 5-6 mins have passed. (00:31:30 - 00:34:10)
Continuity mistake: Grace Park comes out of the water and punches a guy; the part of the surf with the red and black logo faces up. Then she picks it up, and, in a way that does not register right consider her motion and the rotation, that side of the board is facing her. Another cut, and the board is facing the opposite direction. (00:28:20)
Continuity mistake: When Danny and Steve are standing dressed like dorks in the parking lot outside Kamekona's joint, behind them on the left there's a guy who is changing bathing suits using a towel to cover himself. When they speak with the pesky kid the guy finishes his deed and leaves, but when Danny reaches inside the car for the big pink fuzzy thing, that guy is back in that spot. (00:26:05)
Continuity mistake: When Steve McGarrett takes the picture of the footprint, what is photographing is different from what was shown earlier; the print and the objects to the left shifted - easy to tell using the tiles as reference, since in the picture the heel of the foot stops right at the line between two tiles, while it went well across it in the original shot. (00:10:50)
Continuity mistake: Danny and Grace get up to go buy some nachos; at the cut, both Chin and Steve's hands have changed position. (00:01:55)
Continuity mistake: When Steve and Danny enter Bar 35 it's daylight, and when they leave after no more than a few minutes it's completely dark.
Loa'a pono ka 'iole i ka punana. - S10-E13
Other mistake: Grover is going through the personal effects of a victim. He picks up a phone, attempts to open it and declares it locked. When it is put in the evidence bag, you can see it is open. (00:13:10)
Ihea 'oe i ka wa a ka ua e loku ana? - S10-E12
Factual error: A CIA officer stops McGarrett and companions from entering a house to make an arrest. The mistakes here are numerous: 1 - The "CIA officers" have protective vests that say "CIA" on them. No such thing. 2 - They are carrying weapons. Only officers in the Security Protective Service and those officers in a war zone carry weapons. 3 - The CIA is not a law enforcement agency. The FBI handles matters domestically. 4 - The CIA's responsibility is to collect intelligence and information overseas. Last I looked, Hawaii was part of the United States. (00:33:10)
Ihea 'oe i ka wa a ka ua e loku ana? - S10-E12
Factual error: Higgins gets counterintelligence documents from an operative. The document says "CLASSIFIED" at the top. A real document would have the actual classification, e.g., TOP SECRET - NOFORN; SECRET, etc. on it and not the word "classified." To make matters worse, at the bottom the word is misspelled "CLASSAFIED" (00:27:30)
Ihea 'oe i ka wa a ka ua e loku ana? - S10-E12
Factual error: McGarrett and Magnum pull up to a house in the Ferrari. Sound effects are squealing brakes. Brembo Ferrari brakes do not squeal, especially at such a slow speed. (00:14:55)
Ihea 'oe i ka wa a ka ua e loku ana? - S10-E12
Visible crew/equipment: McGarrett and Magnum are working together in this crossover show. They leave a suspect's house and before the scene changes they are outside, and through the door windows you can see a crew member through the glass moving right to left. This is supposed to be an empty house. (00:19:00)
Hana Mao 'ole ka ua o Waianae - S9-E25
Other mistake: When McGarrett and Danny are on their way to the airport where Ian Wright is departing from, there's a shot of their black Camaro sliding through a corner. When they arrive at the airport it's not the same vehicle. (00:31:00 - 00:31:37)
Ne'e aku, ne'e mai ke one o Punahoa - S10-E8
Other mistake: Five-0 discover the camouflaged crash of a Cessna supposedly carrying 170 pounds of heroin (as mentioned previously) in the jungle. The heroin is indeed discovered inside the plane, but the heroin is still neatly stacked in the back seat, even though it does not seem to have been secured. Related, a DEA agent had mentioned that there was 100 million dollars worth of heroin being brought to Hawaii. 170 pounds has a street value (according to the DEA website) of $800,000 per 20 pounds. This would only be $6.8 million, not $100 million. (00:25:30)
Chosen answer: They are Junior's SEAL buddies.
