In mid-June, Bold Nebraska — a grassroots environmental organization opposed to construction of the Keystone XL tar sands pipeline — obtained documents that detail how local and federal law enforcement agencies, as well as the company responsible for building the pipeline, are working together to undermine peaceful political protest.The documents revealed that the company, TransCanada, had briefed the FBI as well as law enforcement officials — district attorneys, attorney generals and county sheriffs — in Oklahoma and Nebraska on the potential threat posed by environmental activists and local landowners. In their PowerPoint presentation the company suggested that district attorneys should explore “state or federal anti-terrorism laws” in prosecuting activists and provided a crude dossier on the key organizers. They also included a list of individuals previously arrested for acts of nonviolent civil disobedience in Texas and Oklahoma.There is a long history of corporations and the state acting in concert to suppress environmental activism. But in recent years the relationship has deepened. This is in part a function of the post-9/11 national security state, which has placed a premium on information sharing between Department of Homeland Security fusion centers, local law enforcement officials and the private sector.
