Yes but this isn't a Laci Peterson after-she's-gone-missing sighting or the Ghost of Natalee Holloway.
This is a witness that spoke with Tony Gatto, at length, on the record (albeit anonymous), who Tony has vouched for incessantly. She spoke of LS's extremely impaired condition before it was widely accepted by the general public.
She spoke of eyes rolling, stumbling, and being completely out of it, BEFORE she was reported missing, not AFTER (like Laci).
Don't forget that LE referred to that video as existing. "... she does appear in that video with someone that is already known to investigators ...". But they discredit the time: I cant say that she didnt see Lauren, Qualters continued. It does not appear that she saw Lauren at the time that was reported by other sources.

LE has not discredited the story. On the contrary, they were vague and ambiguous, as if purposely trying to brush that little witness thing under the rug. And maybe it is indeed - as someone had said before - their trump card. They don't want the public focusing on it because it is or could end up being a big part of their case.
And to this day, the last corroboration of Lauren's whereabouts that LE lists is at 2:51am.
You said before JR would have no reason to lie about her being at his apt around 4am - but that is uncorroborated as well. Yet you believe that, but not the witness testimony?
For me, the witness thing is still huge.
