Disney has countered claims that it enroned twenty boxes of documents pertaining to the merchandising rights to Winnie the Pooh by showing evidence that AA Milne's agent's heirs (who assert that they own the rights in perpetuity) acquired their most damning evidence by digging through Disney's trash and sneaking into Disney offices. Huh? How is this a defense? "Sure, we destroyed documents that were harmful to our case that the other side has brought forward, but they acquired the illegally destroyed documents by nefarious means!"
(Thanks, Zed!)
