Clearly it is imperative that the manufacturers of body armor show that they take a round at point blank range to show the effectiveness of their product.

Live Leak released this video of an Italian manufacturer firing 10 rounds at their human guinea pig, whom we assume or at least hope is a higher up in the company if not anowner. While we don't see car manufacturers putting their Executives in harms way to test out safety features, the old adage still stands for marketing sake, "You could learn a lot from a dummy".
