In 2000 Jason Vale, Christian Bros. was ordered by a New York Federal judge to stop selling apricot seeds as an unapproved \\\"treatment\\\" for cancer.  The FDA says he disobeyed the order and has put him in jail. 
What is noteworthy is that he was denied bail on appeal because of Jury Nullification.  Says the FDA press release: 
\\\"The jury announced the guilty verdicts on July 21, 2003, following the conclusion of a week long trial. During the trial, supporters of Vale had handed out leaflets to persons who entered the courthouse, including a number of the jurors who were deciding the contempt case against Vale.  The leaflet told jurors that they had a constitutional right to ignore the evidence and the Court\\\'s instructions if they so chose. This incident was one of the factors taken into consideration by Judge Gleeson in ordering Vale held
without bail pending his sentencing.\\\"

Note please the the FDA does not say that there is no constitutional right of the jury to make a finding of \\\"not guilty\\\" despite the law and the facts. That\\\'s because there is such a right and it is clearly a threat to the powers-that-be.
