The fourth amendment stops police and other government officials from searching us and our property without probable cause (this includes students). The school can only search you if they have probable cause that you have violated a law or school rules. In the Supreme Court case, New Jersey v. T.L.O., a vice principal discovered marijuana in a student’s purse while searching for cigarettes. The court ruled that students do have Fourth Amendment rights to freedom from unreasonable search and seizure. School officials don’t need the normal standard of probable cause to justify searches, a lower standard of “reasonableness, under all the circumstances” is enough. School lockers are considered the schools property and can be searched within the school’s discretion.
