The Fourth Amendment was ratified in 1791 as part of the Bill of Rights and reflects the Founding Fathers' concerns about government overreach and abuse of power.
Key Supreme Court cases such as Mapp v. Ohio (1961) established the exclusionary rule, reinforcing that evidence obtained illegally cannot be used in court.
The concept of 'reasonable expectation of privacy' emerged from court interpretations of the Fourth Amendment, guiding decisions on what constitutes an unreasonable search.
