DOJ: We don't need warrants for e-mail, Facebook chats | Politics and Law - CNET News.

The Department of Justice, and other Government agencies, will always take the default position that they do not need a valid search warrant to look at digital data such as email, Facebook or other social media posts or anything placed online by the author. There is a conflict between this position and privacy advocates who argue that the new emphasis on cloud computing has put much information in which the user has a "reasonable expectation of privacy" in the ether where it can be discovered and claimed by anyone. Of course, the sticking point is what we consider "reasonable". The Fourth Amendment states:
The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.[1]
Social media, and other Internet based methods of communication were certainly not contemplated by the founders. However, the principle is the same. Citizens have the right to maintain private information. The question becomes whether, in the modern era, it is reasonable to protect information that we voluntarily place in the cloud. I always will default to the position that my private information, wherever I choose to store it, belongs to me until a Judge, after a probable cause hearing, says it doesn't.
What do you think, dear reader?
