If one person has ever been detained at gunpoint without being murdered,seems to me the "pro Aubrey had no choice but to attack" deal is doa.
You would also have to assume that everytime a gun is used to detain,that person is murdered.
You also need to assume that a gun is not a method to detain.
THEN I can proceed under that logic.
Not the real world.
Actually,if this is the modern logic,I am actually More PRONE TO pulling the trigger if the population of the usa thinks I am there to murder 2 or three men breaking into my house at night.
