State v. Todd Lee Kramer, 2009 WI 14, affirming 2008 WI App 62
For Kramer: Stephen J. Eisenberg, Marsha M. Lysen
¶18 Historically, we generally have interpreted Article I, Section 11 to provide the same constitutional guarantees as the Supreme Court has accorded through its interpretation of the Fourth Amendment. Arias, 311 Wis. 2d 358, ¶20. We have interpreted Article I, Section 11 to provide the same constitutional guarantees as the Fourth Amendment provided even before the Supreme Court’s decision in Mapp v. Ohio, 367 U.S. 643 (1961), applied the Fourth Amendment’s guarantees to the states under the Fourteenth Amendment.  Arias, 311 Wis. 2d 358, ¶20. On only one occasion, in our development of Article I, Section 11 jurisprudence have we required a showing different from that required by the Supreme Court’s Fourth Amendment jurisprudence. We did so in regard to our development of a good faith exception under Article I, Section 11. State v. Eason, 2001 WI 98, 245 Wis. 2d 206, 629 N.W.2d 625 (creating two additional requirements under Article I, Section 11 for law enforcement before according a good faith exception to their reliance on a defective no-knock search warrant). Eason has no application here. Pursuant to our usual practice, we shall interpret the provisions of the Fourth Amendment and Article I, Section 11 as equivalent in regard to community caretaker analyses.
