This seems like a pretty good analysis (amended shortly thereafter by the "bring a long gun to a fight" mandate!). I do have at least one issue with it, and that is shooting for the cerebral area. I respect Mr. Carlin for the good info he usually posts, but I respectfully submit that virtually
any mention of the fabled "one shot stop" in any situation aside from a surgical intervention in a hostage situation is unrealistic. Aiming for a smaller target is not the answer. Shooting for a large vital area with a shoulder arm is.
Comments regarding the foregoing analysis of what went wrong and flames cheerfully accepted.
