ACLU To Release Documents on FBI Spying Next Week, Social Activist Groups Allegedly Targeted

The latest batch of documents, parts of which the A.C.L.U. plans to release publicly on Tuesday, totals more than 2,300 pages and centers on references in internal files to a handful of groups, including PETA, the environmental group Greenpeace and the Catholic Workers group, which promotes antipoverty efforts and social causes.

Many of the investigative documents turned over by the bureau are heavily edited, making it difficult or impossible to determine the full context of the references and why the F.B.I. may have been discussing events like a PETA protest. F.B.I. officials say many of the references may be much more benign than they seem to civil rights advocates, adding that the documents offer an incomplete and sometimes misleading snapshot of the bureau’s activities.

“Just being referenced in an F.B.I. file is not tantamount to being the subject of an investigation,” said John Miller, a spokesman for the bureau.

But the documents, coming after the Bush administration’s confirmation that President Bush had authorized some spying without warrants in fighting terrorism, prompted charges from civil rights advocates that the government had improperly blurred the line between terrorism and acts of civil disobedience and lawful protest.

A.C.L.U officials said the latest batch of documents released by the F.B.I. indicated the agency’s interest in a broader array of activist and protest groups than they had previously thought. In light of other recent disclosures about domestic surveillance activities by the National Security Agency and military intelligence units, the A.C.L.U. said the documents reflected a pattern of overreaching by the Bush administration.

“It’s clear that this administration has engaged every possible agency, from the Pentagon to N.S.A. to the F.B.I., to engage in spying on Americans,” said Ann Beeson, associate legal director for the A.C.L.U.

The fact that we’re even mentioned in the F.B.I. files in connection with terrorism is really troubling,” said Tom Wetterer, general counsel for Greenpeace. “There’s no property damage or physical injury caused in our activities, and under any definition of terrorism, we’d take issue with that.”

Jeff Kerr, general counsel for PETA, rejected the suggestion in some F.B.I. files that the animal rights group had financial ties to militant groups, and said he, too, was troubled by his group’s inclusion in the files.

“It’s shocking and it’s outrageous,” Mr. Kerr said. “And to me, it’s an abuse of power by the F.B.I. when groups like Greenpeace and PETA are basically being punished for their social activism.”
