Matt, The practice you describe, called “parallel grounding”, was flawed and discontinued in the 1970s. It was replaced by equipotential grounding, which protects against accidental grid-delivered voltages, but still can’t protect against customer-delivered voltages.

It's the specific combination of current and voltage that is hazardous. Too much current, through/across the heart, is the main, potentially fatal, hazard. This is why 120v GFCIs trip near 5 milliamps (mA). (20-30 mA in the wrong place is too much.) A voltage pushes a current through a
