You state that it's not possible to identify BG by the video, I don't agree. I see RA in the video.
Agreed there will be additional audio and video presented at trial. LE didn't release it in its entirety, but the video is another big brick in RA's wall of guilt.
JMHO
Circling back, just saw this.
As mentioned, it's my understanding that the BG altered video (2 sec clip) can't be admitted at trial. (sorry if I'm repeating myself.)
I realize a lot of folks feel like they can "see RA" in that video. A lot of folks saw RL in that video as well.
I'll share my thinking: There's been no State disclosure on the changes made to the original image in order to create the 2-second BG avatar. We know it's been enlarged, enhanced, edited and cropped to serve as an avatar to encourage tips. No doubt the image did it's job: encourage more local tips. IMO, it's not an identification tool.
I see: a dressed blob: a blue-jacket, jeans, boots, possible hat, hands in pocket, head down, comfortable/steady on the bridge, white dude, likely. (Which I think ... is a pretty good amount of information, but also, could be a lot of folks.)
While Libby's full video (if shown at trial), may also not be a useful "BG = RA" hard identification tool (what expert would go there?) ... Certainly, BG's clothing type and color can be determined. (And that's useful given RA's admissions.) We'll have to see if there's expert opinion on height/weight based upon that original video. I would think an expert could explain the estimated height/weight for BG that's been provided and provide an opinion as to RA's 2017 match to that estimation. Maybe that is wishing too much, though. RA's 5'5", and BG's never been that short.
Regardless, I'd agree that Libby's BG video from her I-phone is a BIG BRICK. Especially as to a timestamp. It
is a brick as to LE's storyline of the bridge abduction. If the word "gun" is audible via Libby's video - that audio (and timestamp) there's a huge brick for the kidnap charges.
IMO, the original video/audio are an important piece - of the circumstantial case.
