Metal detectors are allowed in many states. Courts have ruled that a metal detector is less of an invasion of privacy than other kinds of searches. Metal detectors cannot be used selectively, i.e., on a certain group of students and not others. Tracking systems are all right if the students are separated on the basis of learning ability and not on a racial, ethnic, or gender basis. Moreover, any tracking system used by a school system must ensure that all students are given the same basic education.
