 FAIR: Emil says that he will fake insanity and have himself declared  unfit for trial. This, he says, will result in his being committed  to a psychiatric institution where he will miraculously recover and  be protected from further trial by the "double jeopardy" laws. While  his being "unfit for trial" would, indeed, prevent him from being  tried, meaning that "double jeopardy" wouldnt apply, we can,  perhaps, excuse his incomplete grasp of the subtleties of foreign  law and language, and accept that his plan would work if he stood  trial and was declared "not guilty by reason of insanity".
