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.

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)

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: 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)
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.
Chosen answer: They are Junior's SEAL buddies.
