Trivia: Kam Fong (Chin Ho) actually was an HPD officer for over fifteen years.
HPD told me that in an email a couple of decades ago. Back in the early 80s I read an article about how visitors to the island would call Hawaii 5-O to respond to crimes rather than HPD. I sent them a routine email back aarond 2005 to ask if that still happened. They replied that it did.
