"3 Click Rule"

As I was reading on various sites about technology in the classroom, I came across a post by Will Richardson (http://www.weblogg-ed.com/2006/03/01#a4754) which I was very shocked by. The post discusses how he recieved an email from a teacher very upset about how their district had banned the use of blogs in the classroom, but the most surprising thing was that the district created a "3 Click Rule". This "3 Click Rule" says that all websites will be banned which could be 3 clicks away from a porn site, this shocks me! Not only is this irrational, as Richardson points out, but it's unfair to the students and teacher. First a porn site is not always 3 clicks away, a student could just type in the address of a site, even if it is innocently, and the result could be pretty dramatic. But the point is, Google, MSNBC, education sites, and so many other resources would be blocked, how could one even get on anything on the internet!!! I just can't believe this logic, although I understand the motivation to protect the children, the way in which this school district chose to do so seems irrational. I hope that they district will see the problem with this rule and quickly turn it around. Technology is so important in society today, how can the public school system opt out or remove a such a great educational resource.
