Did Captain Westbrook Watch Tippit's Murder?

[Albert Doyle]

But Lee still has the revolver he used to kill Tippit. What does he do with it?

There's problems with this. The original bullet casings found at the scene were swapped if you examine the evidence. If it were as simple as Lee shooting Tippit in order to set-up Harvey they would have just left the casings as they were.


It doesn't really matter because once you realize there were 2 Oswalds at the Texas Theater you've got all the evidence you need.
