If I remember my history correctly, the whole idea behind firearms was to make projectiles fast and hard enough to overcome body armor and field fortifications. The purpose of bullets has ALWAYS been to overpower resistance and wound or kill your opponent, when used in a combat envionment. To the best of my knowledge, home defense and homeland security are both potential combat enviornments.
So, after centuries of this common sense being common knowledge, some media attention-craving idiots are proposing that nobody (at least us civilians) needs firearms that can penetrate body armor, even after proving that bad guys wear body armor, hide behind hard obstacles, and that the forces of law and order cannot and will not guarantee our protection.
Can somebody bring me up to speed on these new revelations? I seem to be missing the point.
