Mother Jones has a blockbuster scoop today on the private security firm that spied on green groups on behalf of corporate clients:

A private security company organized and managed by former Secret Service officers spied on Greenpeace and other environmental organizations from the late 1990s through at least 2000, pilfering documents from trash bins, attempting to plant undercover operatives within groups, casing offices, collecting phone records of activists, and penetrating confidential meetings. According to company documents provided to Mother Jones by a former investor in the firm, this security outfit collected confidential internal records -- donor lists, detailed financial statements, the Social Security numbers of staff members, strategy memos -- from these organizations and produced intelligence reports for public relations firms and major corporations involved in environmental controversies.

A must-read.
