You bring your predigested arguments to the fray and overlook the elegant simplicity of the statement which is not an argument.

It is a statement of fact.

People are the killers
Guns are the extremely efficient and effective tools.

The problem is the willingness of the people to be the one.
The problem is also the ready availability of the other.

Many problems can't be solved by addressing only one of the above. They HAVE to be dealt with by addressing both.

This means there must be accurate data collection.
There must be education.
There must be regulation.

Until all of those are faced and dealt with the problem will not go away.

A lot of the other statements only spread heat, not light. The lack of understanding of the aphorism above only underlines the truth:

Guns don't kill people.
People kill people.
Guns just make it very very easy.

An extremely well known and somewhat influential wingnut made an erroneous and dangerous aphorism:

"To stop a bad guy with a gun, it takes a good guy with a gun."

It completely ignores the likelihood that the gun can change a non-killer into a killer by its availability. I'm thinking abourt an old duffer who had his gun in a movie theater and shot someone who was merely being a pest. It's as simple as observiing that if your only tool is a hammer, your problems take on the appearance of nails. Once the duffer had shot the nuisance guy, it was retroactively a case of self-defense. Because, now, it had to be.
