"You might not think of the Fourth Amendment while you're using Facebook and other online tools, but you probably should."
The concept of privacy seems to be changing with the advent of social media. When you post online using social media do you think you are giving up your privacy rights?
And here is the 4th Amendment: 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
This article suggests that sharing things online cold infringe upon your 4th amendment right. I think that it is a problem because people do just share whatever photos they want to, no matter how personal. Everyone can view this information without a Warrant, so it is questionable what else they could expect you to let them view without one.
