In the course of doing research for this article, I ran across pieces from EFF and Peacefire (plus one e-mailed lecture) saying that all censorship is bad that we should simply educate our children and coworkers on responsible cyber-surfing, blah, blah, blah.... It's true, and in an ideal world, we could do that. Unfortunately, the world is not populated by only responsible adults and well-educated children. And everyone makes a typo once in a while. Thus, we are forced to do something about it.
The Children's Internet Protection Act mandates that a school or library must have an Internet safety policy, must hold a public review of that policy and must use a "technology protection measure" on all computers connected to the Internet. Whether and how that software can be disabled on certain computers is a local decision. It does not mandate that software be perfect; indeed, many web pages, both administrative and commercial, emphasized that filtering would not be perfect. More on that in a minute.
