A Rock Solid Alibi.....

[Alan Ford]

How would your fantasy conspirators even know who took pictures and films that needed to be doctored?

Another Smith Strawman........ The conspirators behind the assassination were not trying to frame Mr Oswald as gunman. The 'investigating' authorities were, after the event.

Imagine the plan.  Months or even years are devoted to framing LHO for the assassination.

~Yawn~

See above.

Your position is: 'I cannot explain the shadow down Lovelady in Wiegman but I know the image hasn't been doctored because I know the shadow down Lovelady must have an explanation that doesn't involve the doctoring of the image so I'm going to keep deflecting from the issue of the shadow down Lovelady in Wiegman that I can't explain'

How realistic is it that he went from the top of the steps to the second floor lunchroom before Truly and Baker got there, and no one saw him?

He went up to the second-floor lunchroom to buy a coke BEFORE the P. Parade

[Charles Collins]

He went up to the second-floor lunchroom to buy a coke BEFORE the P. Parade

He was stopped by Baker and Truly in the second floor lunchroom immediately after the motorcade passed by the TSBD.

Could it be they were all focused on other things and simply didn't observe him? Many people simply do not notice things or people that are close to them and many also simply do not recollect information.
_Correct.
  AKA 'inattentional blindness'

Inattentional 'blindness' might have been a factor if indeed Oswald was outside (but not noticed) as some here are arguing
The same kind of argument may be applied re inattentional deafness and the stairs

In any case:

So what? What does that tell you about when he got to the lunchroom?

Not according to Officer Baker's same-day affidavit. But by all means continue in your happily subcritical Warren Gullibility, Mr Collins!

Except that it was impossible to be quiet on those old wooden stairs. Dorothy Garner told Barry Ernest that she knew the girls had gone down (before she saw Truly and the police man come up) because she heard them on the stairs. There is no way that anybody could have run down those stairs without making a noise.
