The document provides information about police stop and search powers in the UK. It discusses the main statute that allows police to stop and search individuals, the Police and Criminal Evidence Act 1984. It outlines some of the key safeguards in place, such as requiring "reasonable suspicion" and limiting the degree of force police can use. It also discusses additional statutes that grant police expanded stop and search powers in certain contexts like anticipating violence or terrorism. The document appears to be teaching materials on stop and search law for students, as it provides case examples, self-study questions, and guidance for applying the legal standards to hypothetical scenarios.
