A standard and overused trope in action movies is where Antagonist threatens to do a Bad Thing in his dying breath unless Protagonist drops his weapon. In a movie I saw this weekend it was done twice in the breadth of fifteen minutes, first where Primary Goon threatens to cut the throat of Love Interest, and later where Antagonist threatens to detonate a bomb. Naturally, in all scenes Protagonist has a pistol drawn and cocked, and being a highly trained special forces operative, can be presumed to be capable of putting two rounds into a head sized target from ten feet even under the worst circumstances.
So the question is, what are the chances that the hostage(s) are put in danger by putting a bullet or two into Antagonist’s brainpan? Could a nervous reaction at death be coordinated enough to slit a throat/press a button/trigger? What is police protocol in this kind of situation (hostage in direct danger, police have an unhindered shot at the perperator)?
