Gun Stats/Arguments
I put together what I felt to be a fairly well balanced research on the matter for an Ethics professor of mine in college.
First off, forget about "guns save lives". It is very difficult to prove this conclusively. "Guns save lives" is about as illogical as the argument that "guns take lives" firearms are lifeless, inanimate tools, incapable of distinguishing between criminal and upstanding citizen. People who refuse to be victims save lives. Resting the crux of your argument on this idea is a poor decision, and forces you to argue from a position of weakness; you will always be on the defensive.
The argument that is easiest to prove, and has the most evidence for it:
Gun control does NOT save lives. [\b]
The case for gun control not reducing crime is *almost* as strong.
There are many, many facts that can be made for arguing this position, the best is contained in Wright and Rossi's research. They began their study expecting to be able to prove that gun control saved lives. They believed (probably correctly) that if they could prove this, that gun control would be *much* easier to pass in America. They failed to do so, and unlike many other researchers, were ethical enough to change their opinions on the matter as a result of their research.
The only other study you *really* need is the more recent CDC study of all gun control laws which concluded that there was not enough evidence to conclude that *any* gun control helped save lives. Basically underscoring the same point Wright and Rossi made some 20 years earlier.
When you argue that "gun control doesn't work" you put *them* on the defensive, and force them to provide evidence that complicated, unenforceable edicts are going to deprive motivated criminals of the mean with which they can do harm.
