But a log in cyberspace of my browsing history isn't papers I own, and it isn't an effect of mine. It's physically on someone else's server and isn't anything I ever owned.The government was clearly limited to what it could do.
"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."
Look at the wording, it was specifically not specific as to what could or could not be searched.
"Effects" or "Papers" definitely count as part of your protection.
Or for another example: I wear a black wristband as a sign of protest. My college says that it's a disruption, I say it's free speech. They respond that since I'm not saying anything or writing anything, it's not technically "speech" and isn't protected. Who is right?
