Newly released documents have revealed the Maryland State Police conducted an extensive surveillance campaign in 2005 and 2006 targeting peace groups and anti-death penalty activists. The documents show undercover agents infiltrated meetings and events of the Baltimore Pledge of Resistance and the Baltimore Coalition Against the Death Penalty. The agents entered the name of one prominent Baltimore peace activist, Max Obuszewski, into a federal database that tracks terrorists and drug dealers. The police continued to carry out the surveillance, even though officers never observed any illegal or criminal activity.
