Protesters calling for the elimination of prisons staged a weekend march in Boston to the site where the American Correctional Association is hosting its annual conference.
The Boston Globe reports more than 100 people marched from Copley Square to Hynes Convention Center on Sunday armed with the message that prisons harm inmates more than they help them.
Group organizers say the protest was intended to challenge the philosophy behind the prison system.
A written statement from the collective said they blame the correctional association for putting a "veneer of credibility and professionalism on rampant human rights abuses in prisons across the United States."
Correctional Association President Mary Livers says ACA organizers gathered this week with the specific goal of improving the country's prison systems.
