From Bryan over at Why Now?
A veteran uniformed police officer stopped by his bank and walked in on an armed robbery in progress. Both the cop and the robber had six-shot revolvers. More than two dozen shots were fired at a distance of less than 20 feet and neither was hit. Fortunately no one else was injured but the bank’s lobby was a mess. The robber gave up after he ran out of ammo, while the office still had bullets. The robber reloaded once and the officer twice during the incident.
An off-duty officer stopped by his favorite bar on his way home after work. Just after he sat down, two men came out of the men’s room and one of them had what appeared to be revolver in his hand. The officer drew his auto-loader and fired 14 rounds at a distance of less than 15 feet. Neither of the men was hit, and they surrendered. The weapon turned out to be a pellet pistol designed to look like a Smith&Wesson large frame revolver. The officer was a member of his department’s pistol team and a range instructor.
These were trained police officers that I personally have seen group their shots on a timed course at 75 feet. When confronted with a shoot situation, their accuracy disappeared. You have to be a stone-cold killer not to experience an adrenalin surge and a blood pressure spike in a life or death situation. You experience hearing loss and tunnel vision as your brain stem prepares the body to fight or run by diverting blood from ‘unnecessary’ systems. Training reduces the problems, but they can’t be eliminated.
Given these realities, what are the realistic chances of someone with less training and seasoning than an NYPD SWAT officer being able to make the head shot required to take out a shooter wearing soft body armor and firing an AR-15 at you? An armed guard at that school would have been the first person to die, and wouldn’t have prevented anything. The shooter knew what was going to happen, and that is a huge advantage.
