Dan,
Other than that, I agree that Oswald leaving the TSBD so quickly is troublesome and does not bode well for him being an innocent bystander.
Martin,
I'm not so sure he did.
It's a question of when the building was sealed off. The earliest I can place that is when Lumpkin arrived at 12:49.
When he did arrive, he ordered Lt. Kaminsky to stay at the front door. Inspector Sawyer ordered the building sealed off, but that was only after he had been inside, been up to the 4th floor or so, and returned back outside to the sidewalk.
In his after-action report, Lumpkin wrote:
"Lieutenant Erich Kaminski was placed on the inner door of the building...As each office and floor was cleared the employees were stopped by Kaminski and Mr. Truly at the front door where their names, addresses and telephone numbers were written down, and they were identified by Mr. Truly as to their employment.?
In his Report on the Interrogations of Oswald, Harry Homes wrote of his interrogation on November 24th, ?...when he (Oswald) went downstairs, a policeman questioned him as to his identification, and his boss stated that ?he is one of our employees? whereupon the policeman had him step aside momentarily. Following this, he simply walked out the front door of the building..?
