I guess that that's the privilege of policing for some profit

from Killer Mike – Reagan Lyrics on Rap Genius

Meaning

Police get away with a lot of things that the average citizen wouldn’t. There are a lot of factors involved in this: (rich, white) people think you should respect police because they enforce the laws. Additionally, being a cop is a job that conveys an ability to use force more frequently than other people, frequently with less provocation.

This is a continuation of the last line. Crooked cops are gaining more profit by being crooked because, depending on the city you live in, the base salary for a uniformed officer isn’t all that high and having a badge allows you the privilege to get away with murder (figuratively and literally).

I also believe that the “profit” refers to a for profit, private prison system that was instituted under Reagan.
