From The Rutherford Institute:

The U.S. Supreme Court has refused to hear the case of a Texas man whose home was subject to a no-knock, SWAT-team style forceful entry and raid based solely on the suspicion that there were legally-owned firearms in his household. In denying a petition for certiorari in Quinn v. Texas, the Court let stand a lower court ruling that essentially makes lawful gun ownership and possession grounds for police to evade the protections afforded by the Fourth Amendment and improperly penalizes and limits the Second Amendment right to bear arms.
