Michigan v. Fisher

Police responded to reports of Jeremy Fisher (defendant) screaming and throwing objects inside his home, and upon arriving found blood on a damaged pickup truck outside and observed Fisher inside with a cut on his hand. Fisher refused officers entry and told them to get a warrant, but Officer Christopher Goolsby opened the door and entered, at which point he saw Fisher pointing a long gun at him. Fisher was charged with assault with a dangerous weapon and firearm possession during a felony, and moved to suppress evidence of the gun pointing on the ground that Goolsby's entry violated the Fourth Amendment; the trial court agreed and excluded the evidence, and the Michigan Court of Appeals affirmed.
