And in New York, the New York Police Department has released new internal memos that show police commanders recommended the continued use of covert surveillance, psychological operations and what they called “proactive arrests.” The memos were released after a judge ruled they were relevant to a lawsuit brought by 16 people arrested at an animal rights demonstration outside the World Economic Forum in 2002. The memos include details of how police officers infiltrated political gatherings and monitored the behavior of peace groups. Police have also encouraged “undercover officers to distribute misinformation within the crowds” — a tactic that was disavowed thirty years ago.
