US scientists reveal bulletproof T-shirts

This is simple physics 101. When a bullet is "stopped" by something, all of it's kinetic energy is captured and absorbed by whatever, (whoever), stopped it. Without multiple layered absorption, the blunt force trauma would be tremendous, regardless of how good the "miracle material" was at stopping it. Modern police body armor dishes out the equivalent of a 90 MPH Major League fastball, blunt force trauma to the body from a 9 MM hit.  Bill T.
