As I said: can't give good answers in this simple format --- way too complex questions (even though I realize that you cannot know what you're asking.) I will violate my standards now with the strong hope that you will not take my shallow thoughts too "authoritatively."
What can I say?: Let me make a scattered list and see if it goes anywhere.
A. The researcher handles all UFO claims identically. Whether a distant object or a CE4, they are all approached similarly in general outline. All UFO cases if they are to be given any importance must have "STRANGENESS" at some significant level, and CREDIBILITY at some highly respectable level. This is why a military case with testimony of officers that the objects flew their pants off begins with such strength.
B. CE4s hardly lack for STRANGENESS in the reports so we can forget that half of this for this discussion. That leaves CREDIBILITY. We research credibility in any case that we take seriously.
C. How? Who is the person doing the claiming? Are they respected by colleagues, employers, neighbors --- yes there is often such a detective element in the heavyweight cases (softly done if possible, but some "character" elements looked for.) This is why so much weight is placed on military and police witnesses --- character check comes almost automatically. Are there multiple witnesses? Betty AND Barney Hill; Two independent (hardly knew each other) witnesses at Buff Ledge; Walton and the lumber team; Three Kentucky ladies in their automobile, etc. Almost never is a CE4 independently attested, though Buff Ledge is the White Crow here. LOTS of other types of close encounters have independent witnesses. Is the commentary of the witness consistent over several weeks? Does the witness claim great things for themselves? Does the witness try to make a buck out of it? More importantly, is the witness in a place, time, and circumstance before, during, and after the claimed event that has solid real world context for them in their lives? Lastly (not really, I'm just quitting), if there is other supportive evidence (traces, even bad photos let alone radar and military instruments) these things are NOT the "proof" but if they fit the flow of the report they help corroborate it. NOBODY views any civilian photography as "proof" given what you can do. Shallow debunkers throw that red herring up all the time in their intellectual laziness.
D. CE4s have this extra ingredient of the witness not having much conscious recall. This is why I tend to toss them in the gray basket. But others like hypnosis so they use it. There is a LOT of BAD hypnosis going on out there, plus ever since Hopkins'first book there has been a game plan for any wannabe to follow to get taken seriously by bad researchers. (BIG story there and I am NOT going into it.) Betty Hill herself wrote to UFO researchers warning them that bad hypnotists were roaming around screwing up people's heads. And many people's heads are already screwed up --- a test of a bunch of CE4 claimants shows a way-abnormally-large amount of PTSD AND Child abuse in the cohort. People can choose to dance with some of that in more than one way. I do not. I view it as possible bad contamination and don't like it.
..... and I don't need it. I know what the objects can do. Don't know HOW they do it, but damm sure WHAT they can do. I also know that what's behind them has had (and demonstrated --- see Minot) plenty of opportunity to really mess us up, and has not done so. But folks argue: you don't know what's inside! The CE4-ers do! Do they? Even if I credited the stories, why would I assume that "The Great and Powerful OZ" was showing ANYONE the real stuff behind the Curtain (inside the craft)? The game has been a display performance. It shows us what IT can do, but nothing ever about how it does it. .... and isn't that exactly what we'd do?
Anyway --- I have to be done. This is far more complicated than even that last gush can honorably say.
p.s. Old Man has badly hurting muscle and big pain for several days. I hitting the sack. If you respond and think I'm ignoring you, well, I guess, in some sense I am. Wish me luck on the sleep; have to set up Mass tomorrow morning for Father Don here ---probably a mixed blessing.
