Good point. Gun control advocates, though well-intentioned, are hopeless naive. If someone is willing to disregard laws against murder, sexual assult, and robbery, they're not going to observe gun laws. But a criminal is far less likely to attack someone if they suspect that person has a gun.
IMHO, the entire 'gun control' debate is pretty lame. These people, some well-intentioned, many insanely radical, make so many screams against gun ownership b/c:
"Guns are used to kill people"
"guns were originally made to kill people"
"Guns provide the means by which people kill"
"Gun accidents kill innocent people and children"
Hence, they should be banned or regulated. Point out to them that far more people are murdered by other means than guns, i.e. stabbing, beaten to death (fists, bat, stick, etc), so we should therefore regulate or ban baseball bats and knives?
And they still come back around to defend their stance on gun control, when guns aren't even the most common killer. Funny, I guess murder with a gun is worse than murder with a knife?
