You have no privacy on the Internet - if you're in Pennsylvania

A SUPREME COURT: INTERNET USERS CONSENT TO MONITORING
The Supreme Court of Pennsylvania has held that an individual using the Internet should reasonably expect that his communications are monitored by police. In Commonwealth v. Proetto, a man convicted of soliciting a teenage girl on the Internet argued that it was illegal for law enforcement officers to monitor his Internet communications without a warrant. Though the court chose not to issue an opinion, it ruled in favor the police, finding that there is no reasonable expectation of privacy on the Internet and that the police did not break Pennsylvania's wiretap law when they monitored the man's online communications.
