tells us don't argue with a gun - you will lose

If some one has brought a gun to bear on you at close range you are as good as dead. You must run. Without hesitation.

If you run you have about a one in eight chance, if you fight -- less than half a chance. I do not know what the odds are for standing in front of a gun and waiting for the man who points it to kill you but it is much less than one in eight. Better than fighting, but significantly worse than running.
