Your post indicates a gross lack of well researched info on both UFO's and cattle mutilations.
There are plenty of physicists and the like among witnesses as well as people employed in the field who have spoken up--some on video and in other documentation.
The farmers who have observed the cattle mutilations on their farms 100% as in ALL--a rare statistic--ALL have cited enormous differences between varmit mutilations and the 'other' mutilations. And, when vets have been brought onto the scene post haste, the vets have affirmed that no varmits could have done such.
There have been numerous cases where animals were observed lifted into the sky by unseen means. And that later, the animal had obviously been dropped from high above and there were absolutely no tracks in the snow or mud anywhere near the animal other than the animal's own tracks.
Also, there has persistently been an absolutely uncommon and unfathomable capacity to totally drain the blood from the mutilated animals. The common saying with serious firmness was that there was not a single drop of blood left in the whole animal. Varmits don't do that.
Senator Schmidt sp? of New Mexico sponsored an extensive investigation into the mutilations in our state as there were so many. There was a significant amount of publicity about it from beginning to half way point. Then it began to be clear that nothing very revelatory was going to come out of it. In fact, my own reading on the result was that they found out more than they wanted to find and were desperate to muffle it up as though there was nothing to report.
I don't recall exactly how they did that. But they sure didn't want to go on record about anything very accurate and serious. It was clear to anyone with half a micro-gram of discernment that they had gotten far too close to a topic they didn't want near if they valued their lives and positions.
I now know someone who knows folks who can do some checking on that as well as on Dulce for me. But I have to take it very slow and gently.
Actually, I suspect trailer park folks are under represented. There's a relatively high percentage of policemen, military folks and other such trained observers very well represented in those with significant UFO experiences/observations.
Supposedly, Jews and Roman Catholics are also underrepresented in abduction cases.
