New Tech Puts the Brakes On Bullets Fired From Police Sidearms

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.

      (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.

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.

    The problem I see is though, when a law abiding citizen walks into Lowe's or Chipotle's brandshing his piece as is his second amendment right and in his camos how are the other law abiding citizens in the same place going to know if he is a good gut or a bad guy?

    Therein lies the problem. If I'm concealed carrying at the moment, they are going to have about a second to convince me they are not entering with harmful intent. At that point, it's now a really bad situation.

    This is not a trivial problem.

    It is a trivial problem. You and those like you merely have to stop assuming they're the only good person on Earth.
    Someone should have to prove they're entering with harmful intent before you assume they're not. Assuming they're bad until they somehow prove otherwise to you is a problem with you, not society or anyone else.
