BOSTON (CBS) – Another week, another school shooting, this time a flat-out massacre at a Florida high school. And along with the gruesome predictability of the crime is the ritualistic dance our politicians always go into following a travesty like this.

We could talk about the phony platitudes coming from too many of the pols, and how the record shows their thoughts and prayers for the victim turn into “no” votes when bills restricting gun access surface.

ar15 Keller @ Large: Why Its Stupid To Arm Public With Military Type Weapons

But instead, I want to share with you part of an email I received from a viewer who describes himself as a “conservative, 2nd amendment advocating gun owner who believes it is beyond stupid to arm the public with military-type weapons” like the AR-15, the gun of choice for many of these schoolyard mass murderers.

He writes:

“We will never be able to get all of these types of weapons off the streets but we could reduce their lethality. The current ammo used in these weapons was designed to inflict the maximum amount of damage to the human body and other human bodies nearby. The round is a full metal jacketed high velocity round designed by the military to tumble on impact, causing the bullet to destroy flesh and organs. Do we really need a round like that for target or hunting or even home defense?”

No sir, I think it’s simple common sense that we don’t.

And while that only seems like part of the answer, it’s a more tangible solution than what I’m hearing from most of the endless debate over a problem that we created through negligence and political malpractice, and urgently need to rectify.

  1. In fact, Mr. Keller, there are lots of different types of ammunition available for the AR-15. Not all are full metal jacket, nor is an FMJ round necessarily the deadliest. Full Metal Jacket bullets neither flatten nor expand, so the military uses the to comply with the Hague Convention.

    As for tumbling on impact, there doesn’t seem to have been any consideration given to that in the design. The military uses FMJ bullets since they do not flatten or expand in the body and therefore comply with the Hague Convention. The amount of tumbling depends on several things, including the “twist” in the barrel.

    So I suggest you don’t publish or accept assertions from random internet responders without verifying them. You may safely assume I’m a random internet responder.

  2. Please don’t educate Mr. Keller as to what a ‘hollow-point’ is…..he’s already terrified of FMJ rounds….the kind police have been using for decades.

    The danger of AR 15 ammunition is due to its speed. It leaves the barrel at 3 times the velocity of a handgun around Mach 3. Energy goes as velocity squared, so it just has a lot more energy. When it enters the body the shock wave of that occurs due to this energy can affect tissue inches away. You could miss a major artery or organ with the slug, but the shock wave could tear it apart anyway. The weapons system is designed to give you the maximum probability of killing or disabling your target, which is what you want in a military weapon. It is also easy to use, as it has next to no kick, so beginners are likely to be lethal. We should come together and figure out how to keep these killing machines out of the hands of seriously disturbed people.

    I am also a random internet responder in the spirit of full disclosure.
