In a loss for child molesters or those attempting to molest children (and advertising that on the Internet), the Wisconsin Court of Appeals handed down State v John David Ohlinger, 2008AP135. Ohlinger's horrific personal legal history can be see (partially) on Wisconsin's Circuit Court Access. In any event, the Ohlinger decisions upholds Wisconsin law, which allows police to listen to any phone conversation as long as one party consents to the police listening. If the person consenting to the police listening happens to also be a police officer (rather than a private citizen), that doesn't matter as long as they are a party to the phone call.
