When Police Come to the House
W.S. 7-20-102 — an arrest without a warrant for domestic violence within the past day
Beyond the usual arrest powers, a peace officer may arrest without a warrant, even for something the officer did not see, on probable cause that a household member committed domestic assault, domestic battery, aggravated assault or reckless endangering within the preceding twenty four hours, or is doing it now.

The Fourth Amendment draws its firmest line at the entrance to a home, and the Supreme Court of the United States has held where it falls in situations police meet at a door. Absent consent or exigent circumstances, officers may not enter a home without a warrant to make a routine felony arrest. Where one occupant consents to a search of a shared home and another who is physically present expressly refuses, the search is unreasonable as to the one who refused. And officers may enter without a warrant when they have an objectively reasonable basis for believing someone inside is seriously injured or imminently threatened with such injury. Those holdings are a floor: a state's own constitution and statutes can give more protection than they do, never less.
How a warrant is served is also measured by the Fourth Amendment. The Supreme Court of the United States has held that whether officers knocked and announced their presence before entering is part of whether the entry was reasonable, and that the knock and announce principle forms part of that analysis rather than being a rigid rule without exceptions. Those holdings are a floor: a state's own constitution and statutes can give more protection than they do, never less.
