So he is lying now?
Either Captain Fritz is lying (he is good at that), or Mr Oswald is lying (ditto)!
If the latter, then it is because Mr Oswald realises he has been stitched up and has calculated that his best defence for now is to deny having brought a bulky package to work.
You want to force into his hands on the morning of 11/22 a bag much longer than that seen by Mr Frazier and Ms Randle.
I--------on the other hand--------believe he had in his hands a bag perfectly consistent with the bag seen by those two witnesses.
That's just one of the several reasons why I'm winning here, and you and your pals are losing!
