Göransson reports having used a “high-energy missile” for the task, which is less drastic than it suggests. What it suggests is that Dr. Göransson got into his car, drove some distance from his laboratory, and launched the Swedish equivalent of Tomahawk missiles at the hapless swine, but in fact, I am told, the term simply means a small, fast-moving bullet.
Instantly upon being hit, all but three of the pigs showed significantly flattened EEGs, the amplitude in some cases having dropped by as much as 50 percent. As the pigs had already been stopped in their tracks by the anesthesia, it is impossible to say whether they would have been rendered so by the shots, and Göransson opted not to speculate. And if they had lost consciousness, Göransson had no way of knowing what the mechanism was. To the deep chagrin of pigs the world over, he encouraged further study.
Proponents of the neural overload theory point to the “temporary stretch cavity” as the source of the effect. All bullets, upon entry into the human form, blow open a cavity in the tissue around them. This cavity shuts back up almost immediately, but in that fraction of a second that it is agape, the nervous system, they believe, issues a Mayday blast—enough of one, it seems, to overload the circuits and cause the whole system to hang a Gone Fishing sign on the door.
These same proponents believe that bullets that create sizable stretch cavities are thus more likely to deliver the necessary shock to achieve the vaunted ballistics goal of “good stopping power.” If this is true, then in order to gauge a bullet’s stopping power, one needs to be able to view the stretch cavity as it opens up. That is why the good Lord, working in tandem with the Kind & Knox gelatin company, invented human tissue simulant.
I am about to fire a bullet into the closest approximation of a human thigh outside of a human thigh: a six-by-six-by-eighteen-inch block of ballistic gelatin. Ballistic gelatin is essentially a tweaked version of Knox dessert gelatin. It is denser than dessert gelatin, having been formulated to match the average density of human tissue, is less colorful, and, lacking sugar, is even less likely to please dinner guests. Its advantage over a cadaver thigh is that it affords a stop-action view of the temporary stretch cavity. Unlike real tissue, human tissue simulant doesn’t snap back: The cavity remains, allowing ballistics types to judge, and preserve a record of, a bullet’s performance. Plus, you don’t need to autopsy a block of human tissue simulant; because it’s clear, you just walk up to it after you’ve shot it and take a look at the damage. Following which, you can take it home, eat it, and enjoy stronger, healthier nails in thirty days.
Like other gelatin products, ballistic gelatin is made from processed cow bone chips and “freshly chopped” pig hide.[24] The Kind & Knox Web site does not include human tissue simulant on its list of technical gelatin applications, which rather surprised me, as did the failure of a Knox public relations woman to return my calls. You would think that a company that felt comfortable extolling the virtues of Number 1 Pigskin Grease on its Web site (“It is a very clean material”; “Available in tanker trucks or railcars”) would be okay with talking about ballistic gelatin, but apparently I’ve got truckloads or railcars to learn about gelatin PR.
Our replicant human thigh was cooked up by Rick Lowden, a freewheeling materials engineer whose area of expertise is bullets.
Lowden works at the Department of Energy’s Oak Ridge National Laboratory in Oak Ridge, Tennessee. The lab is best known for its plutonium work in the Manhattan (atomic bomb development) Project and now covers a far broader and generally less unpopular range of projects. Lowden, for instance, has lately been involved in the design of an environmentally friendly no-lead bullet that doesn’t cost the military an arm and a leg to clean up after. Lowden loves guns, loves to talk about them. Right now he’s trying to talk about them with me, a distinctly trying experience, for I keep shepherding the conversation back to dead bodies, which Lowden clearly doesn’t enjoy very much. You would think that a man who felt comfortable extolling the virtues of hollow-point bullets (“expands to twice its size and just thumps that person”) would be okay talking about dead bodies, but apparently not. “You just cringe,” he said, when I mentioned the prospect of shooting into human cadaver tissue. Then he made a noise that I transcribed in my notes as “Olggh.”
We are standing under a canopy at the Oak Ridge shooting range, about to set up the first stopping-power test. The “thighs” sit in an open plastic cooler at our feet, sweating mildly. They are consommé-colored and, owing to the cinnamon added to mask the material’s mild rendering-plant effluvium, smell like Big Red chewing gum. Rick carries the cooler out to the target table, thirty feet away, and settles an ersatz thigh into the gel cradle. I make conversation with Scottie Dowdell, who is supervising the shooting range today. He is telling me about the pine beetle epidemic in the area. I point to a stand of dead conifers in the woods a quarter mile back behind the target. “Like over there?” Scottie says no. He says they died of bullet wounds, something I never knew pine trees could do.
Rick returns and sets up the gun, which isn’t really a gun but a “universal receiver,” a tabletop gun housing that can be outfitted with barrels of different calibers. Once it’s aimed, you pull a wire to release the bullet.
We’re testing a couple of new bullets that claim to be frangible, meaning they break apart on impact. The frangible bullet was designed to solve the “overpenetration,” or ricochet, problem, i.e., bullets passing through victims, bouncing off walls, and harming bystanders or the police or soldiers who fired them. The side effect of the bullet’s breaking apart on impact is that it tends to do this inside your body if you’re hit. In other words, it tends to have really, really good stopping power. It basically functions like a tiny bomb inside the victim and is therefore, to date, mainly reserved for “special response” SWAT-type activities, such as hostage rescue.
Rick hands me the trigger string and counts down from three. The gelatin sits on the table, soaking up the sunshine, basking beneath the calm, blue Tennessee skies— tra la la, life is gay, it’s good to be a gelatin block, I…
BLAM!
The block flips up into the air, off the table, and onto the grass. As John Wayne said, or would have, had he had the opportunity, this block of gelatin won’t be bothering anyone anytime soon. Rick picks up the block and places it back in its cradle. You can see the bullet’s journey through the “thigh.” Rather than overpenetrating and exiting the back side, the bullet has stopped short several inches into the block. Rick points to the stretch cavity. “Look at that. A total dump of energy. Total incapacitation.”
I had asked Lowden whether munitions professionals ever concern themselves, as did Kocher and La Garde, with trying to design bullets that will incapacitate without maiming or killing. Lowden’s face displayed the sort of look it displayed earlier when I’d said that armor-piercing bullets were “cute.” He answered that the military chooses weapons more or less by how much damage they can inflict on a target, “whether the target be a human or a vehicle.” This is another reason ballistic gelatin tends to get used in stopping-power tests, rather than cadavers. We’re not talking about research that will help mankind save lives; we’re talking about research that will help mankind take lives. I suppose you could argue that policemen’s and soldiers’ lives may be saved, but only by taking someone else’s life first. Anyway, it’s not a use of human tissue for which you’re likely to get broad public support.

According to the Kind & Knox Web site, other products made with cow-bone-and-pigskin-based gelatin include marshmallows, nougat-type candy bar fillings, liquorice, Gummi Bears, caramels, sports drinks, butter, ice cream, vitamin gel caps, suppositories, and that distasteful whitish peel on the outside of salamis. What I am getting at here is that if you’re going to worry about mad cow disease, you probably have more to worry about than you thought. And that if there’s any danger, which I like to think there isn’t, we’re all doomed, so relax and have another Snickers.
