who is the bad guy in the negotiator
The Negotiator Believing that Sabian and the police cannot resolve the situation, the FBI assume jurisdiction over the operation, cease negotiations, relieve Sabian of his command, and order a full breach. As Roman prepares for his eventual arrest, Maggie tells him that Niebaum also worked at his house and could have kept Roenick's wiretaps there. Sabian confronts Roman to warn him about the breach, and Roman reveals that the corrupt Officers murdered Niebaum and the executed hostage is still alive and gagged. Sabian begins to believe in Roman's innocence and gives him a chance to prove his case: while the FBI and SWAT raid the building and rescue the hostages, Roman disguises himself as a SWAT member and escapes. Roman and Sabian proceed to Niebaum's house, but they can't find the wiretaps. The police arrive and the corrupt officers enter the house, but they back off as Frost enters and tries to talk Roman down. Sabian observes Frost discreetly taking one of the loaded guns, and realizes that Frost is the ringleader of the conspiracy, the insider on the disability fund's board and Roenick's killer.
