He kohu puahiohio i ka ho'olele i ka lepo i luna - S10-E17
Factual error: Thieves make off with 10 million dollars transferred to an offshore bank. The money is shown supposedly in a medium-sized black satchel carried in one hand by one of the accomplices. The largest US bill in circulation is the $100 bill. And one million dollars in $100 bills weigh 22 pounds. So ten million would weigh 220 pounds. There is no way that amount would fit in such a satchel, and much less be carried around dangling by one hand.
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)
Ne'e aku, ne'e mai ke one o Punahoa - S10-E8
Factual error: The Five-0 team is discussing the helicopter incident where three people were killed. Junior states that they could find no prints or DNA at the helicopter. Yet the helicopter was full of blood, and the perpetrator (seen later) was covered with bloody wounds. It would have been impossible NOT to find the killer's DNA at the very least in the blood. (00:08:30)
Factual error: McGarrett is reviewing a brief on a suspected cartel operative. He shows a picture and says it is called a "tela de araña" saying it is a spider web. Wrong. A spider web in Spanish is a "telaraña", all one word. (00:05:13)
Factual error: A man gets out of his car and identifies himself as a Special Agent. He shows McGarrett a badge and an ID card identifying him as a Special Agent of the CIA. There is no such thing. The CIA does not have Special Agents. They have Operations Officers. And it would be extremely unlikely they would have a badge, as they are not law enforcement officers. (00:01:45)
E Uhi Ana Ka Wa I Hala I Na Mea I Hala - S10-E3
Factual error: HPD's cyber unit is allegedly tracking an IP address, but the address onscreen starts with 258. Impossible, as IP addresses only go up to 255.
Factual error: The plane taking McGarrett from Panama to Mexico purports to be owned by a Mexican fishing company. But the registration number on the plane starts with an N and has 5 numbers and a letter. First of all, a Mexican aircraft would not have a registration number starting with an N. That is reserved for aircraft of US registry. All that aside, the registration number is invalid. US aircraft have at most five characters after the N. The registration - as I suspected - was shown to be in an invalid format when queried in the Federal Aviation Administration database. (00:11:18)
Chosen answer: They are Junior's SEAL buddies.
