As a general rule, police officers cannot enter a home without a warrant. While exceptions do exist, they are somewhat rare and are better left for another blog post. Once a police officer obtains a search or arrest warrant, the officer must comply with all procedural guidelines governing the execution of warrants. If officers disobey these guidelines, any evidence seized as a result of the search or arrest may be deemed inadmissible by the court. In addition, a defendant can challenge the issuance of the search warrant in certain circumstances.
One issue that frequently comes up is when police officers can forcefully enter a home to execute a search or arrest warrant. Generally speaking, if a valid warrant is issued, officers may approach the house named in the warrant and enter that home. However, under New York law, a police officer must first knock, announce their presence as police, and give the occupant an opportunity to answer before entering forcefully. This is known as the “knock and announce rule.”
New York Laws sections 690.50 (search warrants) and 120.80 (arrest warrants) provide for the specific procedures that must be followed when executing a warrant. Both statutes require an officer serving a warrant knock and announce their presence, and both statutes also contain exceptions when an officer is permitted to forcefully enter a home without first complying with the knock-and-announce rule.
