Mr. Mansfield taught us more then just speech at San Ramon High School, he gave us life lessons that still ring true today.  On the first day of class, he suddenly excused himself from the room, and just before walking out the classroom door, he told us not to look inside the top right hand drawer of his desk.  This, of course, had the desired effect on the class. The drawer was swiftly opened, as Mr. Mansfield calmly stood in the doorway, laughing at the ease of our manipulation.

In a classic case of shutting the barn door after the horse has left, the Obama administration and the Department of Defense have ordered the hundreds of thousands of federal employees and contractors not to view the secret cables and other classified documents published by Wikileaks and news organizations around the world unless the workers have the required security clearance or authorization.

"Classified information, whether or not already posted on public websites or disclosed to the media, remains classified, and must be treated as such by federal employees and contractors, until it is declassified by an appropriate U.S. Government authority," said the Office of Management and Budget, which is part of the White House, to agency and department heads, urging them to distribute it to their staff.

The directive applies to both government computers and private devices that employees or contractors might have, as long as they are accessing the documents on nonclassified government networks. It does not advise agencies to block WikiLeaks or other websites on government computer systems, a White House official said Saturday. And it does not prohibit federal employees from reading news stories about the topic. But if they have "accidentially" already downloaded any of these documents, they are being told to notify their "information security offices."

The Department of Defense, in its own directive to military personnel and contractors, says that simply viewing these documents, without proper authorization, will violate long-standing rules even though they are accessible to the public at large on Internet sites.

"Viewing or downloading still classified documents from unclassified government computers creates a security violation," a spokeswoman said in a statement on Saturday.
