Am I Missing Something?

[L Verge]

In flipping through O'Reilly's new children's book on the assassination, I ran across a statement that I never remember seeing before. He discusses Booth's flight out of the back door at Ford's, hopping on the horse, AND THEN heading up the alley to TENTH STREET, where he is stopped by an impromptu torchlight parade of revelers. He then wheels around and heads up the alley to F Street.

To my knowledge, the alley to F Street was the only outlet from Baptist Alley behind the theater. I have never heard mention of an egress to Tenth Street or of a torchlight parade (at 10:30 pm?!) impeding Booth's escape. Have I missed something big all along? What is O'Reilly's source for this? As usual, no footnotes or endnotes...
