NRA cheer leads gun ownership for personal safety. How about responsibility?

As a Libertarian and true believer in our Constitution the bone I have to pick with the National Rifle Association (NRA) is their cheer leading for gun ownership as a means of personal safety. How about reverting back to their original purpose in forming the organization after the Civil War of promoting safe use and responsible ownership? The best that can be expected from the Connecticut Judge's ruling on a trial for the manufacturer of the AR-15 used in the Sandy Hook elementary school massacre is a detailed discovery of the promotional materials used for the sale of this weapon. The NRA should be front and center on disowning the message that is sure to come out in this material.
