Often, the brightest students are doing the mischief, and school officials are struggling to discipline them.

Students who surf sexually explicit sites, for example, have had to write a research paper on victims of sexual abuse.
Six high schoolers were suspended for up to 10 days last school year for posting a list of more than 300 students on the World Wide Web, and suggestions how each one might die.
