copyright laws

So, I have been thinking a lot about the copyright laws that we learned last week in class.   I found them to be somewhat confusing.  The line between what is legal and what is illegal seems almost blurred.   I like that the rules are bent slightly for teachers so that they can share educational sources with their students.   Although I understand that the rules are there for a reason, I think that some of them can be bent a little further as long as there is no trail.  I agree with the rules about computer programs and how they should be purchased for the network.  However, I think it's absurd that you can't put Simba and Nala on your tests to make the them slightly more enjoyable for students.
