It wasn't too long ago, high school students could be caught in classing passing notes to each other.
In today's high-tech world, school officials in three suburban Denver districts say students now are using cell phone text messaging, and sometimes those messages aren't just harmless notes.
Officials say they believe the same right that lets them search a student's locker or backpack for contraband allows them to search a cell phone for text messaging.
Messages could reveal drug transactions, prohibited pornography or even uncover cheating on tests.
The Colorado American Civil Liberties Union objects, saying searches of student cell phones violates their privacy.
