The biggest impression is that this film is satirizing the lack of security caused by the reduction of public finances in the United States.
Several main clues appeared in the process of solving the case: Alex, the murderer in the priest's cellar, Taylor's experience, if any line has enough police force and enough time to investigate, it is possible to reach the final answer. However, after a large number of police forces were dispatched for a few days and the large-scale search was unsuccessful, only Loki was left to follow up single-handedly, and he had no resources to target several suspects at the same time and further eliminate them. (Shows that Loki wanted to follow up on this thread after Alex was released, only to be told not to waste his limited budget)
Loki is a positive character. Loki's identity is a product of the system, but when he faced the powerlessness brought about by the failure of the system, he chose to make up for its insufficiency with all his own initiative in this shrinking system. Loki's classic action in the movie is the blink of an eye - the result of not sleeping for a long time, and after finally finding the little girl, he also endured the pain all the way. The film alludes to the further exposure of the police department's abuses brought about by the reduction of public finances in the United States, the lack of public trust in PD, and the gradual expansion of the crack between the two leading to a vague confrontation, which was finally restored by Loki's positive image. . This also shows that the director's intention is to expose and touch, which can be more carefully understood than a sharp criticism.
