Walt, thanks for the tip I've put it on my list 
Have you noticed that in none of the reports that concern Oswald's interrogations was he asked what the hell he was doing at 10th & Patton?
Really?
No. I've never noticed.... But Perhaps Fritz didn't ask what he was doing at tenth and Patton because Lee had already told him he hadrode a bus from the vicinity of the rooming house to the theater, so Fritz didn't want to reveal the location of Tippit's murder. If Fritz had asked Lee what he he was doing at 10th and Patton Lee of course would have denied ever being at 10th & Patton . ( Truthfully , Because Lee was not at 10th & Patton)
Page 626 WR..... "In response to questions put by Captain Fritz,Oswald said that immediately after having left the building where he worked, he went by bus to the theater where he was arrested; that when he got on the bus he secured a transfer and thereafter transferred to other buses to get to his destination".I believe that he did in fact ride a bus from the rooming house to the theater....but he had forgot to take the transfer with him when he left the rooming house and therefore simply paid the bus fare when he boarded the bus.
Naturally this bit of information has been omitted in the various reports because if Lee rode a bus from his rooming house to the Theater then of course he couldn't have been the man who shot JD Tippit.
Mr. FRITZ. .... I asked him what happened there when he caught the cab and he said there was a lady trying to catch a cab and he told the busdriver, the busdriver told him to tell the lady to catch the cab behind him and he said he rode that cab over near his home, he rode home in a cab.
