When will people learn? This should be part of training for court clerks or whoever redacts documents. Excerpt:

About eight pages of a 51-page government brief filed in federal court in San Francisco on Wednesday were electronically blacked out to protect what prosecutors said was sensitive material concerning a grand jury’s investigation into steroid use in baseball.

But the secret passages can be viewed by simply pasting the document into a word processing program. The passages open a window onto a particularly aggressive government leak investigation, one that seeks to force two San Francisco Chronicle reporters to reveal the identity of a confidential source. They also help explain why prosecutors are pursuing the matter so vigorously.
