The big problem was to many cliffhangers. Dallas gave us who shot JR. Not who shot JR and who knocked up Lucy and will Pam leave Bobby. And just like season two, except for the Kono undercover they tried to clean it all up in one furious hour

Delano is like one of those high overhead/low reward Bond villains. "Okay guys, here's the plan. We're going to spend $29 million on the ship, helicopter, lift crane, aquasleds, SCUBA gear, weapons, and the team of mercenaries, but that last million from selling the meth is all ours to split 17 ways if we don't all get killed breaking into the police station."
Can I use that so I don't have to plagiarizer you?
The freeway shootout was pretty cool, and Chin-Ho straight up executing Delano was hard core. Forensics would totally be able to tell that he shot Delano from a standing position at point blank range, so I don't know if this will be the new season long arc of adversity Chin-Ho has to face in addition to losing his wife and nearly losing his cousin. His conscience getting to him after the shootout could indicate that it will be followed up.
You are leaving out one factor HPD, only the LVPD of CSI comes near the level of corruption among its officers.
