Irresistible Force

Is there some type of discrimination going on at U.S police departments ? Just curious because everytime I see a cop drama from America ( Especially one made as a TVM ) it seems no one can become a detective unless they are a family man with just a few months left in the job , and all police chiefs must be black , while all recruits to the plains clothes division must be females who have a black belt in some martial art

Oh and guess what IRRESISTABLE FORCE is about ? That`s right it`s a TVM with a family man who works as a detective with only a few months left in the job , and his chief is black and he`s assingned a new female partner who`s got a black belt in karate . What else can I tell you ? I can`t remember and I only watched it last night . That probably tells you a lot in that case
