We've seen the response from the media.
At new life church in Colorado in 07, a female usher had a CCW and took down a man with a rifle who had a grudge against the church, but not before he killed 4 people. The mainstream media actually made a pretty concerted effort to under-report to the greatest extent possible (nothing was heard after the initial story, if it was reported AT ALL). Not like these most recent shootings that are getting huge air time.
They dont want to demonstrate that guns can save lives because then they would lose ratings and viewers from the anti-gun community.
