There's a shocking video at YouTube that describes the damage that can be done with a .50-caliber sniper rifle. [View it.]
But the most alarming thing about it is not just that it can cause so much damage and so much injury. The problem is not with military use of this military-grade weapon. The problem is that these same weapons can be easily purchased in the U.S. by virtually anyone. They can be easily purchased by you. They can be easily purchased by that weird guy down the street. And they can be easily purchased by any terrorist who wants to take out a few infidels.
They can be easily purchased because the NRA wants it that way. The NRA believes that taking .50-caliber sniper rifles off the streets will lead to a ban on all firearms. Kinda like how banning over-the-counter sale of morphine has led to a ban on all sales of aspirin, Tylenol, and all other OTC painkillers. Oh, wait. What was that logic again?
