Criminal procedure: warrants; execution of search warrants; modify. Amends sec. 6 of 1966 PA 189 (MCL 780.656).

SB 336 modifies Michigan's search warrant procedures by requiring law enforcement officers to announce their identity and purpose before entering a property, then wait a reasonable time for admittance before forcing entry. It allows exceptions to this rule only in specific situations: imminent danger, evidence destruction risk, or if announcing would compromise an investigation. Officers seeking exceptions must include details about occupants (including disabilities) and animals in their warrant application. The bill directly affects police executing warrants and residents of homes or buildings being searched, aiming to balance officer safety with property occupant rights. The proposed changes are not yet law.
