I don't think the law can be submitted as scientific evidence. (One generally hopes the law is informed by scientific evidence, but even that isn't a given.)

Fundamentally, my point was that there's no scientific basis I can imagine for the idea of free-will, in humans or anywhere else. There's simply no physical law that enables it. (It is, of course, an immensely useful fiction, but that's not my point, which was rather that the entire question of "how to behave rationally" seems to rest on an irrational basis.)

That depends greatly on what you mean by free-will.
