Cops with the Idaho Falls, Idaho Police Department busted in an innocent family’s home, breaking their front door, looking for a third party fugitive. Though the homeowner knew his constitutional rights and demanded a warrant, the cops claimed they didn’t need a warrant because they believe a dangerous fugitive (the girlfriend’s brother) was inside. They did come inside and forced the family outside into the cold for about 30 minutes.
During this time period they handcuffed the dad, even though he was suspected of no crime and there was no search warrant for the home. The problem is, according the U.S. Supreme Court in the 1981 opinion in Steagald v. United States (1981), exigent circumstances to enter a home do not exist merely because the police know the location of a fugitive, even if they possess an arrest warrant for that person. They must also have a search warrant for the residence.
