United States v. Madison [1]

Elliott Madison (also spelled as Elliot Madison), along with Michael Wallschlaeger, was arrested by the Pennsylvania state police after using Twitter messages to relay information from police scanners and maps to protestors of the G-20 summit in Pittsburgh. They were charged with "hindering apprehension or prosecution, criminal use of a commnication facility, and possession of instruments of crime" [2]. According to Martin Stolar [2], Madison's attorney, the charge of hindering prosecution arose from the fact that Madison announced that the police had issued an order to disperse to the protestors.

A week after the G-20 summit arrest, Joint Terrorism Task Force agents searched Madison's New York home and seized his property, including his computers and the records he keeps for his occupation as a mental health facility counselor. Elena Madison, Jennifer Sobolewski, Michael Wallschlaeger, James Weiss, Irina Weiss, and Maik Hasenbank were also residents of this address at the time. The search warrant used in the search "asked for evidence that indicated...[potential] violations of federal rioting laws." If Madison is found guilty of violating the rioting law (18 U.S.C. §2101 [3]), he could face a penalty of up to five years in prison. Madison asked the court for a temporary order [4] to prevent officials from examining the seized property until the court had the opportunity to examine the search warrant.  He also filed a motion to recover the seized property. Stolar argued that the search was unconstitutional and violated Madison's free speech rights [4]. However, an Eastern District New York judge ruled that the government's search was not illegal and lifted the temporary stay [5], finding that the search warrant was "sufficiently particular and in compliance with the First Amendment".

The criminal charges in Allegheny County, Pennsylvania were dropped after the New York investigation commenced, as the law enforcement agencies felt that the G-20 activities "were not isolated incidents." [6] Madison has not been charged in New York yet, and although he has attempted to appeal the court's order, officials are not prohibited from examining the property that they seized.
