I don't know about the Edison story, but 60 cycle, 120 VAC current does tend to be more deadly than higher voltages, last I heard. I worked as a lineman back in the 70s for PSE&G, and my father did the same going back to before WWII. The majority of deaths, at least to line-workers, were from working with 120 VAC, not the high voltage three-phase lines. That because of what it does to the human electrical system that runs the heart. I'm sure some of that is also due the workers being a little less careful when working with low voltage, especially with two bare hands that makes a perfect path through the heart.
120 VAC, along with the inherent resistance of human skin, creates the perfect 120 mAs of current flow through the body to put the heart into fibrillation.
With high voltage, 10 amps will burn something awful, and 20 amps can blow off an arm, leg, or whatever. I've known a few people that got pieces blown off from three-phase high-lines and survived.
