(concurring):
I fully concur in the foregoing opinion.
However, in view of several appeals in this court of late wherein the district courts involved unnecessarily generated problems by succumbing to the impulse to apprise their juries of the courts’ opinion on the sufficiency of the evidence, I suggest great restraint if not abstinence in the use of jury instructions like those set forth in footnotes 7 and 8 of our opinion.
