Do you understand that the judge is requesting something that is impossible? The data simply doesn't exist on WhatsApp's servers. Facebook cannot provide this data, because they don't have it. The chat is fully encrypted from one phone to another, and the unencrypted text doesn't ever touch their servers. Sure, the judge might order Facebook to install a backdoor and be able to grab unencrypted messages off a user's phone in the future. But apparently this is about a case that happened in the past. There is literally nothing they can do. Does the judge not understand this?
