Remember the movie "The Warriors" and if so, how about the concept?

Hypotheticaly speaking, if all the gangs, mafias, outlaw bikers, etc. got together and started "offing" judges, district attorneys, parole and probation officers, and any law enforcement that got in the way---who do you think would win? You know our government would be forced into calling in the military and there would be a revolutionary civil war. I think that it would be an excellent concept for a movie? What do you all think?
