Lawbot and the Case of the Missing Copyright Infringers

>You know that copyright is the key to the kidnappings. The strange thing is that none of the kidnappees other than Copycat had been media shifting. All of the kidnappees did, however, have something in common: they had infringed copyright in one way or another. One had posted a parody of a copyrighted song, another had created a collage that used a portion of a copyrighted photo. You begin to suspect why there have been more Canadian kidnappees: it's the difference between the Canadian Fair Dealing rule and the American Fair Use.

But why?

Do you research the difference between Fair Use and Fair Dealing to get an idea what you're dealing with
or do you look at the past kidnappees to get an idea of who might be next?
