Katz, 389 U.S. at 357, 88 S.Ct. 507. OFAC has directed us to a few cases, however, in which the Supreme Court has analyzed whether a warrantless search was reasonable in the totality of the circumstances — without reference to any specific exception. Samson v. California, 547 U.S. 843, 126 S.Ct. 2193, 165 L.Ed.2d 250 (2006); United States v. Flores-Montano, 541 U.S. 149, 124 S.Ct. 1582, 158 L.Ed.2d 311 (2004); United States v. Knights, 534 U.S. 112, 122 S.Ct. 587, 151 L.Ed.2d 497 (2001). We will assume for the purpose of our discussion (but do not decide) that the “ ‘general Fourth Amendment approach,’ ” Samson, 547 U.S. at 848, 126 S.Ct. 2193 (quoting Knights, 534 U.S. at 118, 122 S.Ct. 587), applies equally to warrantless seizures. But see KindHearts I, 647 F.Supp.2d at 878-79 (<HOLDING>). Under this approach, “we examine the totality
holding where there is no duty to defend there is no duty to indemnify holding there is no requirement that the government obtains a warrant at the first moment probable cause exists  the touchstone for determining the constitutionality of warrantless searches is one of reasonableness under the circumstances recognizing a presumption of reasonableness holding that there is no general reasonableness approach to warrantless seizures holding that reasonableness analysis applies in general jurisdiction case under federal circuit law
