“ The mere invocation of federal power by a federal law enforcement official will normally render futile any attempt to resist an unlawful entry or arrest by resort to the local police; and a claim of authority to enter is likely to unlock the door as well. ”

“ The availability of such alternative means for the protection of privacy may lead the State to restrict imposition of liability for any consequent trespass. A private citizen, asserting no authority other than his own, will not normally be liable in trespass if he demands, and is granted, admission to another's house. ”

This case has its origin in an arrest and search carried out on the morning of November 26, 1965. Petitioner's complaint alleged that on that day respondents, agents of the Federal Bureau of Narcotics acting under claim of federal authority, entered his apartment and arrested him for alleged narcotics violations. The agents manacled petitioner in front of his wife and children, and threatened to arrest the entire family. They searched the apartment from stem to stern. ”

“ United States, 290 U.S. 13, 16, 54 S.Ct. 26, 27-28, 78 L.Ed. 142 (1933) . 'The very essence of civil liberty certainly consists in the right of every individual to claim the protection of the laws, whenever he receives an injury.' Marbury v. Madison, 1 Cranch 137, 163, 2 L.Ed. 60 (1803) . Having concluded that petitioner's complaint states a cause of action under the Fourth Amendment, supra, at 390-395, we hold that petitioner is entitled to recover money damages for any injuries he has suffered as a result of the agents' violation of the Amendment. ”
