At the U.N., at 11:52:36, Tokarev is in a hallway conference with his boss and another delegate when the mate to Jason's phone rings in his pocket. He steps outside to answer, and Jason gives him directions and the skinny on the 911 call. "Then the police are already on their way," Tokarev points out. Jason says he'll just have to take Kiefer out after he's in custody, then. And what could be easier than that? Other than shooting him through his apartment window when he was exposed, unarmed, and carrying a human being, and we know how that went. Tokarev hangs up and walks off, without bothering to report back to his boss. Although I guess they probably don't want that other delegate to know about the secret assassination they're trying to carry out to protect their role in the very public one that happened earlier. Hate for someone to get the right idea.
"Brown jacket, freeze, police!" a uniformed NYPD officer bellows at Kiefer in the bank lobby. As everyone else in the lobby scatters, Kiefer complies with the order to get on his knees and interlock his fingers behind his head with his back to them, cursing silently to himself. At least this way he's in a great position to see Dana walking right past the bank doors on her way to another exit. As one officer approaches to cuff him and the other radios rather prematurely, "We got him," Kiefer grabs the closer officer's hand, twists him around, and holds him hostage with his own gun, using his body to shield himself from the other officer. Keeping his gun leveled, the officer with the itchy radio finger tries to talk Kiefer down, but the only thing Kiefer wants to hear is whether the officer knows who he is, which he does. Kiefer threatens to kill his hostage if his partner doesn't drop his weapon and kick it over to him. The officer complies. "I'm sorry," Kiefer says, and shoots the other officer in the foot. He goes down, and the hostage is unconscious now as well, because either Kiefer had him in a sleeper hold or all the sets in this entire episode are suffused with aerosolized Benadryl or something. Kiefer walks out, unloading the cop's gun and dropping it and the clip on the floor before walking out with his own weapon drawn. On his way out, he tells someone to call an ambulance for the cops. Because he's nothing if not a gentleman.
