A gun is not a tool just like any other. That's specious. Guns make killing more feasible and easier than any other tool out there. With the right gun, you can mow down a crowd of people. You can't say that about a screwdriver or knife.
Any object in the universe can be a tool. Let's drop the relativism and call a spade a spade.
If a gun is just a tool like a knife or hammer then the US military would use knives and hammers when spearheading military operations. It issues guns b/c guns are extremely effective tools for killing.
Why is this point so controversial?
On the other hand, if a gun is merely another tool, what is its use?
What is the function of a gun?
Decker, is a loaded gun sitting on a table or laying on the ground a threat? No, it's not.
A gun, a bladed weapon, lead pipe, whatever is not a danger to anyone until it is picked up and
used as a dangerous weapon.
The "function" of a gun (and I'm talking handguns not shotguns and rifles used for hunting), and I've had this discussion with law enforcement, is self-defense. That's what they use it for and that's what I'd use it for.
Seriously, your argument can be used for basically anything from guns to cars (driven by drunk drivers) to military combative and martial arts training. I have about 6 years of martial arts training and was a wrestler for 6 years. The sole purpose for my Krav Maga training is to seriously injure and, if necessary, take someones life. Does that make me any different from a gun? Oh, and as for the military use of guns... it's the soldiers and marines pulling the trigger of the weapons doing the killing. The "guns" are just the tool used to carry out the task, as you stated, efficiently.
It's all in the intent and use of the tool, buddy.
Anyhoo, have a safe and Merry Christmas and Happy New Year.
