Issue: Whether the exclusionary rule applies where the police relied on judge-made law that automatically countenanced all no-knock entries to search for drugs and that law was subsequently overturned.
Holding: Police action in good faith reliance on supreme court pronouncements insulate that conduct from the exclusionary rule.
At the time of the entry of Ward’s home, the court had upheld a blanket exception to the knock-and-announce rule. Because “the officers’ actions were in conformance with the law in Wisconsin, as articulated by this court, allowing for no-knock entries,” excluding the evidence wouldn’t advance exclusionary rule purposes. ¶49.
