"K is for KENTUCKY V. KING. In an 8-1 ruling, the Supreme Court ruled that police officers can break into homes, without a warrant, even if it’s the wrong home as long as they think they may have a reason to do so. Despite the fact that the police in question ended up pursuing the wrong suspect, invaded the wrong apartment and violated just about every tenet that stands between the citizenry and a police state, the Court sanctioned the warrantless raid, leaving Americans with little real protection in the face of all manner of abuses by law enforcement officials."
