This is my personal favorite. In general, if an ox kills a person, the owner is absolved of responsibility and only the ox is stoned. Except in the following circumstance:

“But if the ox were wont to push with his horn in time past, and it hath been testified to his owner, and he hath not kept him in, but that he hath killed a man or a woman; the ox shall be stoned, and his owner also shall be put to death.” (Exodus 21:29)

Maybe reviving that clause would get people to keep better control over their attack dogs, eh?
