Legislation would clarify the definition regarding personhood if Congress found it necessary. Without such a definition a plain reading of the Constitution establishes protection within the first and fourth amendments, regardless if the citizen is biological or mechanical. Stare decisis dictates that speech applies to thoughts and expression equally, and therefore cannot be restricted, under the reasonable analysis pertaining to the intention of the speech. And, in order for the citizen to be secure in their person, is protected from unreasonable search and seizure.
Mr. Grajek had the authority to form a contractual agreement but could not forfeit his guarantee of speech. The United States similarly could not seize his data despite written consent, as it has not been demonstrated in precedent or law that the information can be distinguished from thoughts, and thus is protected speech.
