Question

Which of the following statements explains the Fourth Amendment's protections against unreasonable searches and seizures? (1
Law enforcement must have a search warrant and/or probable cause to search a person's property.
School officials must have probable cause to search a student's locker.
Law enforcement must have reasonable suspicion to search a person's house.
School officials must obtain a search warrant before conducting random drug testing.

Answer 1

Only statement (1) is correct.

Explanations:
- (1) Correct. The Fourth Amendment generally requires law enforcement to have probable cause and normally a warrant based on probable cause to search private property, though there are established exceptions (consent, exigent circumstances, plain view, searches incident to arrest, etc.).
- (2) Incorrect. School searches require a lower standard—“reasonable suspicion,” not probable cause (see New Jersey v. T.L.O., 1985).
- (3) Incorrect. To search a home, police ordinarily need probable cause and a warrant; reasonable suspicion (a lower standard) is insufficient.
- (4) Incorrect. Schools do not always need a warrant or probable cause for certain drug-testing programs; the Supreme Court has allowed some random drug testing of students (e.g., Vernonia School Dist. v. Acton, 1995; Bd. of Educ. v. Earls, 2002) under a balancing approach.
