What if the person who they had accidentally sent the e-mail to hadn't been a Gmail user but had instead downloaded the message to Outlook on their home PC. Would GS think they could get a court order to search that person's home to retrieve all copies of the message that they might have on their hard drive and backups?<p>For that matter, how do they know that the Gmail user hasn't already downloaded a copy of the message and sent it to somebody? (Most probably, they just deleted it, since it was worthless to them.)
