Scenario #1

You create a web link to the CBS - David Letterman web page, the Right to Life and the Right to Choice web pages on your school's home page.  Your principal instructs you to remove them from the school links.

This does not violate copyright.  No part of the material from any of these pages is being removed from the site by the librarian.  Nor does it indicate that there are any plans for the removal of any of these materials.  There is no indication of any attempt to claim the material on said websites as the school's own.  There are simply links from one site to another to allow the user of the school site to examine information on the other web pages.  The material will be read in its own copyrighted location which is what the creators of the site hoped for and intended.  The only problem the librarian seems to have from this story is a principal who is unhappy with the choice of sites, which may lead to controversy.
 

Scenario #2

Mr. Hamer is tutoring the functional writing test out of a copyrighted series of work books from Houghton Mifflin.  He has 27 students but only 20 books were purchased for his class.  The same material is available at te HM web site. He prints enough pages for his kids each morning for today's class.

This seems to be a clear violation of copyright.  Although he is using the materials for class instruction it seems that in this case he has overstepped the fair use bounds that the lawyer discussed.  Mr. Hamer would notbe allowed to copy from the workbook because it would violate the company's copyrights for that work and if he gets the same material off the web he is doing the same thing in essence.  In addition it seems to violate many of the guidelines set down for how much a person can copy of any work.  If there is a percentage value of some kind then Mr. Hamer's copying of what seems to be virtually the whole book would violate those guidelines.  If people could simply go to the web and freely copy off pages of a text at will why would any school system bother to buy the books anymore?
