BENTONVILLE, ARK. — Wal-Mart won a gag order to stop a fired security operative from talking to reporters and a judge ordered him to provide Wal-Mart attorneys with "the names of all persons to whom he has transmitted, since Jan. 15, 2007, any Wal-Mart information."
The court papers made public Monday follow a string of revelations about the retailer's large surveillance operations and its business plans.
