Meanwhile, protesters arrested at antiwar demonstrations in New York last spring were extensively questioned about their political associations, and their answers were entered into databases. And last week, a federal prosecutor in Des Moines, Iowa, obtained a subpoena demanding that Drake University turn over records from an antiwar conference called "Stop the Occupation! Bring the Iowa Guard Home!" that the school's chapter of the National Lawyers Guild, a civil libertarian legal group, hosted on Nov. 15 of last year, the day before a protest at the Iowa National Guard headquarters. Among the information the government sought was the names of the leaders of the Drake University Chapter of the National Lawyers Guild, its records dating back to January of 2002, and the names of everyone who attended the "Stop the Occupation!" conference. Four antiwar activists also received subpoenas in the investigation.

On Tuesday, after a national outcry, the U.S. Attorney's Office canceled the subpoenas. Still, says Bruce Nestor, a former president of the National Lawyers Guild who is serving as the Drake chapter's attorney, "We're concerned that some type of investigation is ongoing."
