I'm not sure what you are babbling about. Talk about straw man. I accept Frazier's testimony that Oswald carried a long bag that morning. I think he is being truthful about his estimate of its length. He is just wrong which is entirely understandable because it is an estimate of the length of an object that he had little cause to notice at the time.
a) who the hell are you to just declare that he was "wrong"?
b) he didn't just "estimate" the bag. He saw how much of the back seat it took up, and he saw how it was carried. He also saw what kind of paper it was made of and he definitively stated that CE142 was not the same bag. Deal with it.
In contrast, there is no such subjective qualifier to his answer as to when he last saw Oswald. He either saw him after the assassination or he did not. He doesn't have to make an estimate to answer that question. He says in his WC testimony that he did not. That is about as clear as it gets.
And he says in interviews with both Gary Mack and Stephen Fagin that he saw Oswald coming down Houston street. That's also as clear as it gets.
And yet contrarian loons such as yourself are suggesting that Oswald hung around the building until 12:45. By implication that means anyone who puts him on the bus, cab, or boardinghouse (various random citizens) all lied for some inexplicable reason.
No, Strawman "Smith". Whaley put him in the cab at 12:30. That can't be right. Roberts put him at the boardinghouse near 1:00 PM which has no conflict whatsoever with being outside the TSBD at 12:45. Besides, Buell told Gary Mack it was 5-10 minutes after the assassination.
And on and on that fantasy goes. That is just rabbit hole nonsense. Even humorous.
The humorous nonsense is what you arbitrarily try to pass off as fact.
