Nope, Ford didn't shoot 'im
Stipulating per Tom not counting military action, I think Cheney is still the only other VP to shoot somebody. But I get your point about the accidental nature of it...I was speaking tongue-in-cheek when I pointed out Cheney's dubious distinction. Burr actually intended to shoot Hamilton, but as far as we know, Cheney didn't intend to shoot Whittington. I'll split the difference: Buckshot in the heart is more serious than a bonk on the head with a golfball, but it falls a little short of a duel at dawn.
