Deliberate mistake: When Jimmy Dove responds to the bomb in the computer lab at MIT, the camera shows the boyfriend on the floor, dead from a self-inflicted gunshot wound to the head. The pistol is lying next to his head and it is a 1911-type .45 automatic with the hammer down, not cocked. When an automatic pistol is fired the slide automatically cocks the hammer as it moves back. This will happen even if there is only a single bullet in the gun. The hammer should be back in a cocked position.
