Wave Goodbye - S2-E7
Plot hole: For two patrol officers (one of them being kinda green) in Honolulu, Kelly and Jordan sure seem to have the weight of the entire State on their shoulders; they also investigate extensively the murder case, and they, until a month before, "worked drugs in that area", which was a piece of jungle around Maui. It's like the department for this episode and this episode only has no detectives, and a couple of random beat cops are covering the archipelago with highly specialized duties.
