RT Article T1 What does “knock and announce” mean? An analysis ofWilson v. Arkansas and its progeny JF American journal of criminal justice VO 26 IS 2 SP 287 OP 303 A1 Jones, David M. LA English YR 2002 UL https://krimdok.uni-tuebingen.de/Record/1764202988 AB The U.S. Supreme Court held in Wilson v. Arkansas (1994) that the common law “knock-and-announce” principle formed part of the “reasonableness” inquiry under the Fourth Amendment. However, the Court’s opinion gave little guidance as to what would be unreasonable under these circumstances. Some critics expressed concern that this lack of guidance would lead to many variations among lower courts. Other observers discerned a signal that little should be deemed “unreasonable” in the context of “knock and announce.” These criticisms are analyzed through a review of lower court interpretations of Wilson.
