i watch that too... those investigators are not mostly white... a good mix of ethnicities... the perps are almost always black... and so are the victims... and the crimes are often drug-related... what can you do if that's the way it is, right?
First 48 is good stuff. There is a black lady who is an investigator. She is very maternal. I’ve seen her break down these “hard” brothers to the point of them confessing and crying for their momma’s.
