U.S. Schools Are Buying Phone-Hacking Tech That the FBI Uses to Investigate Terrorists

In the case New Jersey v. T.L.O, the U.S. Supreme Court ruled that schools do not necessarily need a warrant to search students so long as officials have a reasonable belief a student has broken the law or school policy, and the search is not unnecessarily intrusive and reasonably related in scope to the circumstances under which the search was originally justified. The “reasonableness” standard is extremely broad, largely deferential to the whims of school officials, and can serve as the basis for fishing expeditions; courts have only rarely ruled that school searches violate the Fourth Amendment.
