Cutting Edge of Secrecy

'Better shred than read' are the new watchwords of white-collar America. But inquiring minds are getting better at picking up the pieces.


Two decades ago, Iranian students who stormed the U.S. embassy in Tehran found a mountain of paper shredded by American diplomats who were trying to hastily destroy secret documents. The enterprising students brought in carpet weavers, who reassembled the papers, strip by painstaking strip.

The result: volume after volume of classified material, made available in those days at Tehran bookstores. The reconstituted documents became collectors' items and added to the growing, and sometimes dubious lore of paper shredding.

Now, bankrupt energy trader Enron is adding its own chapter. Recent revelations paint a picture of corporate shredding machines hard at work even as the company went bust and investigators moved in to examine hundreds of suspicious partnership deals.

Like the Tehran experience, the shredding may be all for naught. Modern sleuthing can overcome some of the most devious destruction. Yet the notoriety of the Enron shredding, like many earlier episodes, is almost certain to enhance the perception that the only safe secret is a shredded secret.

In most corporations, the shredder is now as common as water coolers and filing cabinets. Regularly scheduled shredding sessions can legally dispose of documents that in the future might be subject to a subpoena. Whole warehouses of files, and even defective products, have found their way into gnawing electronic teeth.

The National Assn. for Information Destruction, the industry trade association, estimates the number of shredding companies nationwide at around 600, up from perhaps 25 in the early 1980s. Iron Mountain Inc., one of the largest records-management companies in the world, estimates that American businesses spend roughly $300 million a year on shredding documents.

Increasingly, however, that doesn't mean the data can't be recovered by investigators. Because most documents are created on computers, then passed along electronically, shredding paper copies eliminates only one version.

Sergio Kopelev, an electronic sleuth for Control Risks Inc., an international business-risk consulting company, said chances are good he could come up with a destroyed Enron document by examining the company's computer hard drives. (A computer forensics firm has been hired by the Andersen accounting firm to do just that.)

"It would be complicated because of the sheer volume of data you'd have to process," Kopelev said. "But this kind of procedure is routinely done by computer investigators. I would love to be the one to do it."

Various parties, meanwhile, are trying to sort out what to do with the thousands of strips of shredded material confiscated in the Enron investigation. As matters now stand, the shreds are in the hands of the Milberg Weiss law firm, which represents a former Enron executive who found them.

The strips of paper have been subpoenaed by the Securities and Exchange Commission. Neither the SEC nor the Department of Justice would comment on any plans to reconstruct the documents, though a spokesman for Milberg Weiss said whole lines of type are clearly visible because the documents were shredded horizontally--as were the Iran embassy documents that were reassembled. That embarrassing incident caused American embassies worldwide to upgrade their shredding machines so they produced confetti rather than paper strips.

How shredding began is subject to some guesswork. Shredder importer Jack Preiss says the first commercial patent was issued in 1935, with a concept borrowed from a Bavarian noodle cutter. Other sources put its invention earlier, including one story of an Austrian artillery officer who developed a foot-powered shredder in the late 19th century so he could destroy his ballistics drawings.

Once merely a tool of institutions such as hospitals that routinely destroyed records to protect patient privacy, shredding blossomed into a truly diverse industry after the Watergate burglary in 1972.

G. Gordon Liddy, mastermind of the break-in, shredded as much as he could find that was connected with the botched burglary, including soap wrappers and $100 bills from illegal campaign funds. But he couldn't get rid of everything. Liddy later opined in his autobiography that he could have used a much bigger shredder.

"The year before Watergate, I sold 70 shredders," said John Wagner of Allegheny Paper Shredders, who has installed industrial facilities worldwide. "After Watergate, I sold 400. Everybody's attitude was, 'We've got to have a shredder.' "

Other infamous and market-building shreddings followed. Former Lt. Col. Oliver L. North held a shredding party just before Justice Department investigators began searching his office for evidence in the Iran-Contra scandal. The Bank of Switzerland shredded Holocaust-era documents showing that Nazis forced Jews to sell their property far below its fair value. The Treasury Department fed 162 boxes of American Indian trust fund documents into its shredders in 1998, even as it was accused of mismanaging Indian funds.
