I do, indeed, think that Oswald did exit the building via the front door. Is this a "proven" fact? No. But it is certainly the most reasonable inference to be made from the available evidence (mainly based on the testimony of Mrs. Reid, who saw Oswald walking toward the FRONT stairs on the 2nd floor at about 12:32).
And since we KNOW that Oswald (who was no doubt attempting to get out of that building as quickly as he could following the shooting which was carried out with HIS RIFLE from the sixth floor) did exit the building very soon after the shooting, it doesn't make very much sense for him to go down the front stairs (which is the direction he was headed when Reid saw him), but then reverse his direction and go all the way to the back of the building again so he could exit via the Loading Dock door (which, IMO, would look more suspicious to anyone who might happen to see him leave by that back door right after a Presidential assassination attempt).
So the "reasonable inference" reached by the Warren Commission (and by David R. Von Pein of the Hoosier State) is that Lee H. Oswald very likely departed the Book Depository via the front entrance at about 12:33 PM CST on November 22nd. Your opinion may vary. But if it does vary, it's certainly not going to be nearly as "reasonable" as the "front door" inference.
And, btw, in this thread itself, I never said a word about Oswald leaving by the "front door". All I said was this:
".... Leaving the TSBD Building within about three minutes of the Presidential shooting and then proceeding to walk several blocks east on Elm Street in order to get on a bus that he only stayed on for a matter of a few minutes before getting off and catching a cab at the Greyhound bus terminal (which was likely the only time in his life that Lee Oswald paid for a taxicab ride while in the United States of America)."
I'll accept your apology in advance. 
i offer no apology for stating the very obvious . which is that LN of which you are one push the lone nut warren commission version of events . and as can be seen in your own post david you dont deny that you think he left via the front door 3 minutes after the shooting , indeed you offer that that it is the MOST REASONABLE INFERENCE . so for what reason would i need to offer an apology ? .
but again not one single witness is there in support of oswald leaving via the front door within 3 minutes . Mrs reid never saw what route Oswald took in leaving the building . but is interesting that you would cite her in this case . given that she has Oswald wearing only a white tee shirt not the famous brown shirt . not only that she said Oswald was carrying the coke that LN deny he was holding seconds earlier when baker encountered him .
Mrs. REID. Well, I kept walking and I looked up and Oswald was coming in the back door of the office. I met him by the time I passed my desk several feet and I told him, I said, "Oh, the President has been shot, but maybe they didn't hit him."
He mumbled something to me, I kept walking, he did, too. I didn't pay any attention to what he said because I had no thoughts of anything of him having any connection with it at all because he was very calm. He had gotten a
COKE and was holding it in his hands and I guess the reason it impressed me seeing him in there I thought it was a little strange that one of -the warehouse boys would be up in the office at the time, not that he had done anything wrong. The only time I had seen him in the office was to come and get change and
he already had his coke in his hand so he didn't come for change and I dismissed him. I didn't think anything else.
Mr. BELIN. When you saw him, I believe you said you first saw him when he was coming through the door?
Mr. BELIN. Do you remember what clothes he had on when you saw him?
Mrs. REID. What he was wearing,
he had on a white T-shirt and some kind of wash trousers. What color I couldn't tell you.
Mr. BELIN. I am going to hand you what has been marked Commission Exhibit, first 157 and then 158, and I will ask you if either or both look like they might have been the trousers that you saw him wear or can you tell?
Mrs. REID. I just couldn't be positive about that. I would rather not say, because I just cannot.
Mr. BELIN. Do you remember whether he had any shirt or jacket on over his T-shirt?
Mrs. REID. He did not. He did not have any jacket on.
Mr. BELIN.
Have you ever seen anyone working at the book depository wearing any kind of a shirt or jacket similar to Commission Exhibit 150 or do you know?Mrs. REID.
No; I do not. I have never, so far as I know ever seen that shirt. I have been asked about that shirt before, I have seen it once before but not since all this happened.
do you think the lady you just cited is problematic at all to your stance and version of events you are pushing ? .
