GUNS do not kill people, other people do.
The development of weapons (including guns) served only one purpose and one only. Kill. Guns and other weapons are tools build to kill. We can have illegal or legal, moral or amoral reasons to kill. It doesnt change the fact that a gun is a tool build to kill.
Not a reason to be in favor or against the gun laws.
Just a reason to call that argument fallacious as Marquis2 said earlier.
