I think that the 3rd party doctrine is flawed in that the 4th Amendment specifically states that we are to be secure in our "persons, papers, and effects," which equates to the communications medium of the era of the Constitution's authors, and a parallel can be drawn with the US Postal Service, as our mail is
supposed to be secure against external perusal except when the final provision of the 4th Amendment is met by issuance of a warrant describing the things to be seized or inspected.
The wiretap law should be revised to include other forms of electronic communications in order to thwart such applications of the feeble 3rd party doctrine.
I find it reprehensible that in the "Land of the Free" we allow our government to circumvent the letter and intent of the Bill of Rights in the name of "security" when these very circumventions are the antithesis of freedom.
