A capable marksman? The officer in this story was a veteran SWAT trained officer. He fired 36 of the 40 rounds he was carrying, achieving 14 hits, only 5 of which had the possibility of stopping the fight. All of this to stop just ONE assailant. If you find this guy in your living room at 2am - how many rounds do you want?

So what can we learn from this as it relates to "high" capacity debate?

1. Marksmanship - this officer was a veteran officer and SWAT trained. He averaged almost 50% hits in the adrenaline charged moment of saving his life. That places him far above the average LAPD/NYPD officer who averages only 28-33% hit rate in shootings. If you shoot as well as this officer, you may land 3 hits out of your entire magazine. If you shoot as well as the average police officer, you may land only two hits.

2. A gun, especially a pistol, is not a death ray. It isn't unusual for someone to be shot, even multiple times, and still continue to function. In this case, out of 14 hits, only 5 could have caused a physiological stop and 2 of those 5 would have allowed the assailant enough time to possibly kill the officer. So roughly 1/3 of the hits made were effective. If you get that lucky, you'll need 3 hits to get one hit that may force your attacker to stop 12-15 seconds later.

3. The majority of criminal assaults involve more than one attacker. JohnKSa has done a nice probability analysis that shows a 10rd magazine gives you about a 50% chance of winning a gunfight with two attackers.

Of course, none of that is relevant to Aurora. Giving that person 10 ten round magazines is just as much of a problem as him having a 100rd magazine, probably more since the 10rd mag is actually reliable. Not to mention the entire idea that law-abiding citizens should be treated as potential lunatics. There is no safe amount of ammo you can give to a mass murderer. There is no safe magazine for a murderer.

And lets face it, from a practical perspective, you couldn't get rid of them if you wanted to. Detachable magazines with more than 10 rounds date back to the early 1900s. There are probably hundreds of millions of untraceable "high capacity" magazines out there.
