Body armor is supposed to absorb the energy (that's what hurts) of the bullet, while the impulse is spread over body surface larger than the tip of the bullet... If the bullet is going to be launched back, your body has absorb up to twice (in case of incoming speed = outgoing speed) the amount of impulse. I would rather see the bullet just stopped.

I've learned from 9/11 and the Dorner case is that drivers licenses and passports are the best materials for personal protection.

Even Greenland knows what's going on!

bounce. bounce. bounce.
