William O. Douglas,
Johnson v. United States (318 U.S. 189…
“ It is no answer to say that comment on a defendant's refusal to testify does not in any way place him in jeopardy of being charged with or convicted of the crime protected by his privilege. That may be admitted. The problem here is a different one. It is whether a procedure will be approved which deprives an accused on facts such as these of an intelligent choice between claiming or waiving his privilege. Knowledge that a failure to testify though permitted by the court would be submitted to the jury might seriously affect that choice. ”
