In the above case, I agree with you that the MUTCD will not be binding but the photo provided by the OP might be persuasive in their defense. A fair-minded judge is might well understand that the driver would not reasonably see such a sign and therefore have no awareness of the turn prohibition. Furthermore, if the deputy adds words to his TBD like "clearly indicating" to his TBD response (assuming he does respond), a photo like the one shown here might seriously call into question his credibility.
