The main take away from this episode is that too often "detectives" try to prove their opinion rather than following the facts. In this episode, the team try relentlessly to prove a suspect's guilt when they should have been following the facts. A series of very unprofessional decisions, statements and ill-conceived conclusions result in the murder of the suspect. Very disappointing, but revealing about the failings of human nature. Olivia has the suspect tried and convicted early in the episode. Shameful.
