We do actually know what the father's reaction was to the CCTV footage because RD was interviewed by MSM. He had no reason to lie. He did not get paid for sharing his footage.
There's a lot of mistruths being put out there, but not by MSM who are not going to risk their expensive insurance policies by publishing lies.
It was high definition camera footage. We do not have access to that. RD did and Gannon's dad did and LE did. I think it's useless to speculate on shadowy film that is not even close to the real thing. LE also has access to several doorbell cams in the area, not just one.
In any case, whether he returned or not, he was not seen leaving that house at 3.15pm by anybody or picked up in any camera either.
If the father said she lied about the time, I think we can take it as true.
The abc news report cited here many times states that LE did not dispute RD's findings or conclusions but that they are just a single aspect of their investigation.
I'm not saying anyone is lying. I'm saying we haven't heard any of those things from the actual sources.
I have not heard LE say they don't dispute it, they have only said they have the video and will not talk about the specifics. I think the media has taken that to mean they don't dispute it because they won't discuss it.
