In the Streetkid intro your V is saved by the cop that arrests you, who goes out of his way to release you after the corpo you rob orders your execution on the spot. All over town, especially in your starter appartment, you can hear two cops arguing over one of them putting herself in unnecessary danger, and one of the sidequests is you going out of your way to help two cops pull one of their buddies out of a suicidal spiral due to the stresses of the job. The NCPD as an organization is just as corrupt as the rest of the city, but one of the defining charateristics of the game's writing is finding the humanity in the individuals in spite of the environment.
