Does the exclusionary rule apply to every Fourth Amendment violation?

Not every Fourth Amendment violation warrants suppression. See Illinois v. Gates, 462 U.S. 213, 223, 103 S.Ct. 2317, 76 L.Ed.2d 527 (1983) (The question whether the exclusionary rule's remedy is appropriate in a particular context has long been regarded as an issue separate from the question whether the Fourth Amendment rights of the party seeking to invoke the rule were violated by police conduct.). Exclusion is a last resort, not [a] first impulse. Hudson v. Michigan, 547 U.S. 586, 591, 126 S.Ct. 2159, 165 L.Ed.2d 56 (2006).
