New Tech Puts the Brakes On Bullets Fired From Police Sidearms 369
Zothecula writes: Police officers are trained to shoot for the center of mass, not necessarily to kill, but to stop – although the end result can often be one and the same. "The Alternative" is designed to give officers a less lethal option in the form of a clip-on "air bag" for semiautomatic pistols that reduces the velocity of a standard round to make it less lethal. At the front of the bright orange carrier is a hollow sphere made of a proprietary alloy that catches the bullet and firmly embeds it as it leaves the barrel. The ball and bullet fuse, slowing the round by 80 percent. At this speed, the ball-encased round is less likely to penetrate flesh, but it will transfer enough kinetic energy across a wide surface to knock a suspect down with less chance of a lethal outcome.

You can actually calculate the mass if you have the initial mass of the bullet, it's initial velocity, and the velocity of the combined object after impact. It's a perfectly inelastic collision, after all. Classic physics problem.
It works out that the ball is probably about 30 grams for a 9mm.

Think about this: a typical 9mm round will be 115 grains or 124 grains in weight. One grain is 1/7000 of a pound. We're talking about a projectile going in the ballpark of 1000 fps that weighs only about 0.0177 pounds for the 124 grain bullet. There simply is no knock-down potential.

Re:Bullets don't knock people down (Score:5, Insightful)
(Trigger warning: Physics teacher here!)
Actually, momentum is NOT conserved for the *shooter*. He is bracing himself against something (his feet on the ground, usually), so there is an external force acting on him. Thus, this particular argument fails.
For the victim, if he is shot unawares (so he doesn't brace himself), then conservation of momentum *does* apply. I calculate that he will experience a force to his chest of about 35 newtons (~8 pounds). That's not much, and won't accelerate him much.
However--it may well knock him down. The reason is, the force to his chest will cause a torque on him, which will cause him to rotate down to the ground. If we assume he rotates about his feet, and treat him as a solid cylinder (reasonable approximation) then I get an angular acceleration of about 0.4 radians per second per second (22 degrees per second per second).
That only lasts while the bullet is in contact with him, of course; after that, the victim has a gravitational torque on him, with a corresponding angular acceleration (I estimate) of 9 rad/s/s.
If someone wants to check my work, I'll supply the numbers and things I used. I might well have made a mistake or missed something.

Mythbusters did an episode on this. They had to hit the pig with their biggest rounds while it was wearing armor to knock it down when it was being held up by the most sensitive of systems.
What's more likely is a biological reason for falling down. The body's systems have just been disrupted, and a human stays up only by sensitive balance anyways, it's fundamentally unstable most of the time. Shock, surprise, pain, and such disrupt the balancing act, and they hit the dirt.
That being said, this device seems to be about 3/4 of a beanbag round(calculations here [slashdot.org]), so it's logical to figure that it works much the same way - inflict a sharp blow that causes a muscle spasm [wikipedia.org], or such, disabling the target long enough for officers to move in and finish subduing.

I believe it has something to do with the end of the draft.
When were younger, the police were made up mainly of people who had been in the military. But they had been drafted into the military so the chances were good that a lot of them were just regular people who needed a job and wanted to serve and protect. Today, an even higher percentage of police are ex-military, but these jackoffs volunteered to go to some third-world country to massacre brown people. They probably got turned down by the Blackwater/Xe/Academi type outfits where they could make some real money menacing people, and instead ended up on local police forces, thinking of themselves as some kind of liberating/occupying force in residential neighborhoods. They don't think of serving the public as much as they do fighting the public
There were always bad/brutal cops, but today, it's de rigueur to be bad/brutal.
Having said all that, I live near the Chicago Police Academy, and they're starting to get higher-quality recruits. But the bad/brutal jackoffs are now brass, trained in the First Gulf War, and think every policing issue requires the use of armored vehicles and snipers. So that's how they get trained.
