Must be why we get along so well. We share the same madness.
The cop learned that his pregnant daughter is stuck on that elevator. In a mad attempt to get to the building he sees the jerk who got her pregnant then left her. In a blind rage, he throws all of his values and beliefs out the window and tries to kill him. The jerk dodges just in time and the crowd is none the wiser as the cop barrels off.
See you got me doing it.
