The differences between direct, vicarious and contributory liability, Section 512 in related matters. Alright, now let's move on to the next question, which is criminal liability. You read some material on that. And the basic lessons that I want you to take from the material are the following. First, notice that federal copyright law does not impose criminal liability easily as ordinary laws of tangible property do. And I think that that's a good thing. Remember that guy in Les Miserables who's pursued for stealing a loaf of bread. Stealing in the sense of copying one song would not make you liable for prosecution in the way described, if you didn't do it for financial ends.
