Status Quo: Law enforcement is underworld, and the way to survive is down to earth. "You need to do something bad to gain the trust of the circle, and then you will have a chance to change everything."
Two ways: let go of your hands and feet to get the big deal done. Or stick to it in order to gain respect.
In fact, both must make sacrifices, and should be a compromise.
The veteran is too unscrupulous, playing with laws and ethics, there is no professional ethics, everything can be instrumentalized. This kind of invocation of various methods is the most successful in reality; the problem is that if something goes wrong, no one will help, because he dissolves the trust of others in him, and all friends are based on expedient interests. Novices are ethical and responsible, but they are too innocent and easy to offend other people's interests. He just exists as a professional unit and does not protect his strength and support his own resources. He will soon be killed in life.
In the film, the two people are two extreme exemplary existences, which is impossible to achieve in reality. How to take the golden mean is a profound secular wisdom.
The script is good, face the reality, truthful and powerful.
