There was no consistency in her statements. Saying that she might have caught a fleeting glimpse of Oswald standing on the first floor at 12:25 is not the same as saying that she saw him in the second floor lunchroom at 12:15. Even her statements made in 1978 are not consistent with one another.
Inconsitent would be to deny seeing Oswald in one interview and claiming having seen him in another interview. You are playing word games again, Tim. What the FBI agent wrote in his report is not automatically what she really said.
Brennan's statements are not consistent with one another, so why do you believe him?
