The actor playing the detective harrassing the female is spot on. He can't even speak English and can't see what he is saying is nonsense, but in typical dirty cop fashion, he is insisting that the ends justifies the means, no matter who gets hurt or whose life is destroyed. This is the part of being a cop some people don't understand. If the person is a control freak, they should find a different line of work because people like that are so bent on making a case they become delusional. Anything that is "close enough" to real isn't real, it's not reality and people like that just can't understand. Especially those who came from homes with issues as a kid, they take out their upbringing on everyone else.
