The Anti-Gun View Of Guns

In the hands of a criminal, no matter how untrained, guns are impossibly efficient killing machines. However, in the hands of ordinary people, no matter how well-trained, they are completely ineffective, and can only make the situation worse. An armed citizen will inevitably kill at least hundreds of other innocent citizens should he try to defend himself or others with a firearm. He cannot, no matter what, ever kill an attacker; but he will inevitably wreak havoc on the innocent.
   Fucking guns, how do they work?
