On the rooftop, McClane radios for help. The dispatchers send a patrol car in. Just as the police officer is about to leave, McClane drops the body of a dead terrorist on his patrol car. The LAPD arrive. They send in a tank and four SWAT team members, but Gruber's men beat back both attacks. When Gruber ignores McClane's request to stop attacking, McClane takes some C4 explosives and blows up part of the building.
