The document discusses police stop and search powers in the UK. It outlines that police powers to stop and search individuals come from the Police and Criminal Evidence Act 1984 but other statutes also provide these powers to prevent and detect crime. It notes that reasonable suspicion based on objective facts is required for searches and outlines factors like race, age or appearance that cannot be used alone as grounds for suspicion. The document also discusses voluntary searches, powers to question individuals, case law on refusing to answer questions, recording of stops, and safeguards around providing name/reason for the search.
