This story is sure to bring out all the evil 'hacker' stories, that topic has been a little slow lately. Maybe they should arrest these kids as 'terrorists'. Doesn't the Patriot act make hacking in to a government computer system an act of terrorism?
The real blame should be placed squarely on the shoulders of the administration. What kind of system do they have where a hacker can even change grades through a web interface? If that isn't bad enough, they must not have had backups of the system either. Students are being asked to bring old copies of homework and tests in so teachers can re-calculate their grades.
Ridiculous and irresponsible.
