Ok quick review. The homicide squad are taken hostage by a man whos son commited suicide in prision for a murder he didn't commit. In the hours that he has them hostage the squad figure out who the real murderer is but don't have the evidence. By City Homicides standards this episode has plot holes you could drive a truck through.
1. Apparently if you hold a gun to their head the squad can solve a crime in a couple of hours otherwise they wind up convicting the wrong person.
2. Despite it being a large police station (underground car park, elevators etc) There appear to be only the two uniformed coppers on duty and the three homicide squad members catching up on paperwork (suddenly seems like police work is a nine to five job)
3. There's no real panic or anger when their collegue the uniformed officer is shot (sorry I forget her name). There is no sence of urgencey or fear after this, they seem to have more compassion towards their captor then towards their college.
4. There's no conseqences following their being held hostage, no PSTD from anybody, no big investigations into their security, just back to the job. Not even concern for their fallen collegue she just disappears. In fact they seem a lot more upset that the hostage taker kills himself. An episode such as this should have consequence that continue throughout the following episodes in the series instead it is a stand alone episode.
5. They have Stan handle the negotiations rather then bring in the trained negotiators.
