J.M.H.O. Corduroy but as long as guns are being blamed for this nonsense, it removes some weight off the shoulders of the perpetrator, similar to a see through blouse or short skirt reducing the responsibility on a rapist.
A gun is a tool a murderer uses to commit murder. A short skirt is not a tool used by a rapist to commit rape. A better analogy would be comparing a gun to GHB.
