"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."
Tell us what parts of PRISM adhere to that?
I assume the Prism search warrant said:
Probable cause: Someone in the United States is always breaking the law, and unlimited search warrants might help in finding that person.
Place to be searched: United States of America, including but not limited to all electronic communications originating/terminating/transiting in or through one or more of the 57 states.
Persons or things to be seized: One or more US or foreign citizens, and/or the entire body of their written and electronic communications.
Constitutional Law "Professor" Obama sees nothing wrong with that. It's consistent with the Living Constitution, which means only what the liberal wing of the Democrat Party wants it to mean.
