Top Law Schools

Do any law schools post lectures online on sites like youtube, so students can rewatch them?

Some have something like that called Panopto. Not all professors do it, though, even at schools where it is offered.

My profs at NYU will record classes that fall on Jewish holidays. Those are just audio however.

Rutgers-Camden records every class where the prof approves it (most do). They also record a lot of the major events.

Michigan has a random and weird audio recording system that I get the sense no one really understands.
