At the beginning of the first episode, Detective Collette, who is reportedly highly experienced, knowledgeable, efficient as a detective, is in charge of a raid looking for a wanted suspect. The suspect is confronted, runs, is caught after a struggle. As the officers are holding him, he continues struggling. It apparently never occurs to any of the officers, of any rank, to handcuff him. Instead they scold him and advise him of his "right to remain silent"; which is NOT required to be given immediately upon arrest. The suspect continues struggling, breaks away and runs again.
The efficient, professional detective finds a bag of drugs and and money in her deceased daughter's bedroom. There is no apparent good reason for her to hang on to this bag of loot, yet at the risk of her job, her safety, her life, she doesn't immediately call the police station to report it and have them pick up the bag.
C'mon; I know it's a TV show, but please, a little more realism, especially consistent with the quality of officer they're trying to convey here.
