FBI agents took box after box of address books, family calendars, artwork and personal letters in their 10-hour raid in September of the ... house shared by Stephanie Weiner and her husband. The agents seemed keenly interested in Weiner's home-based business, the Revolutionary Lemonade Stand, which sells silkscreened baby outfits and other clothes with socialist slogans, phrases like Help Wanted: Revolutionaries." The search was part of a mysterious, ongoing nationwide terrorism investigation with an unusual target: prominent peace activists and politically active labor organizers. Investigators, according to search warrants, documents and interviews, are examining possible "material support" for Colombian and Palestinian groups designated by the U.S. government as terrorists. The apparent targets, all vocal and visible critics of U.S. foreign policy in the Middle East and South America, deny any ties to terrorism. They say the government, using its post-9/11 focus on terrorism as a pretext, is targeting them for their political views. The activists have formed the Committee to Stop FBI Repression, organized phone banks to flood Attorney General Eric H. Holder Jr.'s office and the White House with protest calls, solicited letters from labor unions and faith-based groups and sent delegations to Capitol Hill to gin up support from lawmakers.
