There's a lot of "American biscuits are scones" flying around here. But to all the Brits, answer me this: are not scones hard? Like rocks? Surely. Surely, the American biscuit is closer to a bread roll than a scone! It's fluffy. It's soft. It is not a building brick with marmalade! Though, if you put marmalade on one, it is quite tasty.
One might easily beat a man to death with a scone, so hard and dense are they. The only way to kill someone with an American biscuit is to smother it in gravy and serve it with sausage and grits. Even then, it will take time to work its way into the breakfast patron's arteries.
