Once again, you are comparing apples and oranges. If such high strength
construction were to be used in vehicles, it would be applied to both
minicars and 1/2 ton pickups, so in my analogy as amended by you, both
the 98lbder and the linebacker would have padding, since they would both
have "current technology". In such a case, who would be hurt more????
Stop avoiding the answer you know I am expecting....
In the case of you cop/kevlar vest vs. bullet: Its easy to stop a
bullet, as its a puny little thing, and the vest does its job not by
being impervious to bullets, but by being impervious enough that they
don't penetrate all the way through by the time the vest has spread ALL
of the bullets kinetic energy across the wearer's entire chest surface.
TO be able to use your analogy, the cop is the 1/2ton truck, and the
bullet is the minicar. Ever look at what happens to a bullet that hits a
vest???? Is it reusable? I didn't think so. Is the cop reusable? Most of
the time. Thanks for the proof....
