“The privilege against self-incrimination is neither accorded to the passive resistant, nor the person who is ignorant of his rights, nor to one indifferent thereto. It is a fighting clause. Its benefits can be retained only by sustained combat. It cannot be claimed by attorney or solicitor. It is valid only when insisted upon by a belligerent claimant in person. McAlister v. Henkel, 201 U.S. 90, 26 S. Ct. 385, 50 L. Ed. 671; Commonwealth v. Shaw, 4 Cush. 594, 50 Am.Dec. 813; Orum v. State, 38 Ohio App. 171, 175 N.E. 876. The one who is persuaded by honeyed *541 words or moral suasion to testify or produce documents rather than make a last ditch stand, simply loses the protection. Once he testifies as to part, he has waived his right and must on cross examination or otherwise, testify as to the whole transaction. He must refuse to answer or produce, and test the matter in contempt proceedings, or by habeas corpus. The holdings in the cases of this type cited by defendant are sound, but they do not apply here because Memolo did not resist, he acquiesced. Likewise, he did not have himself held in contempt or arrested for refusal. Furthermore, he had the documents in his possession and returned them. Finally, he did testify as to such matters many times before this grand jury and now expressly waives the privilege against self-incrimination as to this testimony.”

United States v. Johnson, 76 F. Supp. 538 (M.D. Pa. 1947)

 

“If there is any fixed star in our constitutional constellation, it is that no official, high or petty, can prescribe what shall be orthodox in politics, nationalism, religion, or other matters of opinion, or force citizens to confess by word or act their faith therein. If there are any circumstances which permit an exception, they do not now occur to us.”
