I have to sign and create CAs (Confidentiality Agreements) for M&A projects.  Loose lips get you fired.  I loved Janie in The American President "I'm not at liberty to speak..."  As for the lookie loos my desk is locked up tight each night and during the day I usually only have current working documents on my desk with others in files.  Even a temporary project gets a file made with a small sticky note as the label so documents are not usually out for prying eyes to see.  Plus being in legal EVERYTHING is considered sensitive.  Fortunately most people are leary of legal and don't "wander" over to our side of the building very often!
