Peter Greene writes about a ruling in Pennsylvania that protects the privacy rights of teachers. The public does not have a right to know where teachers live, i.e., their home addresses. Sounds simple, no?

Today, when there are so many challenges to privacy, this is a ruling that is heartening.

Now, we need parents willing to challenge the right of school districts to agree to the data mining of their students without parental consent.

And parents who will sue when the district gives the names and addresses of their students to charter chains in search of students.
