WASHINGTON, July 17 (UPI) -- Documents released Thursday show that undercover Maryland state police officers infiltrated three local peace and anti-death-penalty groups, attending organizing meetings and sending reports on their activities to U.S. intelligence and military agencies.

The documents, obtained by the ACLU through a Maryland Public Information Act lawsuit, also show that the name of at least one local activist was entered into a federally funded database designed to share information between state, local and federal law enforcement about suspected drug traffickers and terrorists.

The entries in the Washington/Baltimore High Intensity Drug Trafficking Area database for Max Obuszewski list his "Primary Crime" as "Terrorism -- Anti Govern(ment)," and his "Secondary Crime" as "Terrorism -- Anti-War Protesters."

The officers used false names -- referred to in the documents as "covert identities" -- and opened e-mail accounts under them that they used to receive messages from the groups.

"This is not supposed to happen in America," Maryland ACLU attorney David Rocah told United Press International. He called the surveillance -- which the documents show lasted from at least March 2005 to May 2006 -- "Kafkaesque insanity."
