The inside story of how an Idaho toddler shot his mom at Wal-Mart - The Washington Post
It's a terrible situation for the family, especially the child who shot her.
Even responsible gun owners (which it sounds like she was) screw up. So sad.
That aside, I think both of those rules were written in earlier generations when accidental discharges with pistols were far more common. Modern pistols have improved designs incuding a mechanism in revolvers that make it impossible to fire the weapon via the hammer with out pulling the trigger.
Likewise, most, or nearly all, semi automatic pistols have new designs where the hammer is no moved to the "ready position" (I dont know the technical terms) when the weapon is charged. Instead, they are double action.
This is just beyond horrible. She was far from dumb, she was a nuclear research scientist who that day made a poor choice and it unfortunately cost her her life. She had her three other children with her too so they all witnessed that.
Heartbreaking for all involved.

Why do we fall?
So we can learn to pick ourselves up.
Problem is most reporters don't know anything about guns so they don't know how to ask these questions.
I mean there was a case where a guy drop it done and it went off near my house, Took out a leg get a piece of furniture at the cost plus world market at the Silverdale mall, but he was carrying a replica of an 1870s era Derringer, The replicas made for collectors they come with a manual that says do not carry it because they are they do have that problem they will go off if dropped.
