Despite overwhelming public support for drug testing teachers, the school system has its hands tied by the U.S. Constitution, which prevents putting such a system in place.“I wish we could,” admitted Director of Schools Bobby Cox, who has been looking into the possibility of random drug testing for everyone in the school system. “But, the Fourth Amendment is the obstacle since courts have said, in the case of government employees, it is a violation of the Fourth Amendment.”Public sentiment about random drug testing for teachers came to a head after the arrest of a Hickory Creek teacher recently after he allegedly bought drugs on campus. Two other Hickory Creek teachers have been suspended without pay for alleged drug involvement.
