In gun-very-friendly-Arizona, a father and his 4-year-old boy visit a friend. The friend has a gun "for protection" or, possibly, to amuse idle 4-year-olds.
Boy shoots dad. Dad dies. "Just a tragic accident," say police. Move along, nothing to see here.
The National Rifle Association has started a new publicity campaign that goes: "I am the NRA and I believe 'shall not be infringed' means exactly that."
More accurate would be, "I am the NRA and I don't give a damn who gets hurt."
