Seen this movie on either Showtime, HBO or Cinemax in the '90s

This movie had a serial killer and a detective that was trying to track him down. The serial killer visited bondage clubs. The serial killer was a white man. The serial killer wore a suit at most times or dressed formal. The serial killer slit a black mans throat on a live television talk show. The serial killer went after the detectives wife and put her in some kind of trap. At the end of the movie the serial killer had a HUGE shoot out with cops at a party or wine mixer or something like that. This movie has to be from the '80s to the '90s. I seen this movie when I was around 10-15 years old. I am 29 years old now. I hope I gave enough information, I have been looking for this movie for about 5 years. I am thinking that it might be a banned movie, or no longer in copy or released.

Maybe "Jill the Ripper"?

Sorry, but that is not it. I am looking for a movie in the 80s or 90s. Jill Rips/Jill The Ripper is from 2000. Thank you for trying. I wish I had more information on the movie I am looking for, but sadly that is all I remember.
That is not the movie I am looking for either, sorry. Try to make the bondage thing the last thing you look for, it didn't have that big of a part in the movie. In the movie I am looking for they show the serial killer throughout the whole movie and you don't have to guess who the serial killer is.
Maybe "Tightrope"?

I'm sorry that is not it either. It is upsetting that I can't find this movie. I'm thinking that it is a hard to find movie, rare, not in production anymore, maybe banned. I don't think it has any big name actors in it either.
