American decisions that regulate how the police gather evidence: the warning before questioning in Miranda, the exclusion of illegally seized evidence in Weeks and Mapp, stop and frisk in Terry and electronic surveillance in Katz. A case belongs here when its cited article describes it as a decision on search, seizure or interrogation. It excludes cases on counsel and defences. All five are decisions of the Supreme Court of the United States on the Fourth, Fifth or Sixth Amendment limits of police work.
