The problem with this case is, and as Chuz has pointed to with that list of questins, we simply don't know what we don't know. There's absolutely no way to make any determinations with any certainty at all because of the lack of public information. I know I'm repeating myself but that's where we're at here.
People can't just choose what they want to believe to complete the puzzle yet that is the point that we seem to be at.
For the public to aid in this case the public needs more info.
I do question what purpose it serves not to release some or all of the video. If the video shows LS is as incapacitated as some believe it does then it might serve to cause some of the friends of 5N to speak up about things they might know. Maybe they believe them to be innocent and think they've misread something and not want to pile on and misdirect LE (and bring more wrath upon them), but to see that she was incapacitated might cause them to come forward. It might lead them to believe what they know they aren't misreading after all. It could cause them believe it makes 5N look guilty because they are.
OTOH, if she's not as incoherent and incapacitated as some of you have come to believe then it would help the public understand why LE can't discount the 5N story. And maybe something else shown might lead to a tip from the public. Maybe someone else has suspicions about someone they know but believe they are wrong because 5N has to be the guilty party. If the video shows LS' condition to not be as bad as speculated then suddenly their suspicions going in other directions could take on more weight and cause them to report what they've been quiet about. Maybe someone sees a person or vehicle in the video that they know shouldn't be there.
I know there's been a lot of talk about tips lately, but I don't see how there's much chance of any new tips coming in without something new coming into the story.
