PING
That's a big mytery that I've not read any conclusive highly placed sources convincingly assert convincing solid knowledge about.
Some say it's a genetic research study.
Some say it's a food slurry for the ET's thing.
Some say it's a pollution of the biosphere research monitoring study to detect when the point of no return has finally been reached.
Some say the ET's have not said what it's about and that the government has no clue.
Some say the government does it as much as the ET's. I'm skeptical of that.
Some say the government has taken it over and the ET's don't do it any more. I personally highly doubt that.
In any case, it's a highly protected operation. Even the New Mexico Senator using the Government Accounting office to investigate the frequent occurrances and the whole field because of New Mexico's large number of cases--even he got essentially neutered in the process . . . and, interestingly died not too many years thereafter of cancer IIRC. Lots of folks getting close to some such things end up dying of cancer. Not sure why that is.
Linda Moulton Howe--one of the world's experts on the phenomena has also had lots of harrassment from powers that be whenever she began to get too close or publicize too much about it.
Of course the more sobering thing is the significant number of cases where humans are mutilated in precisely the same ways as the cows--and it's clear that there was no anasthetic and that the humans were alive and conscious for the process until sufficient blood was drained to end their consciousness and lives. Great fun having one's genitals and rectum; an eye and half a jaw highly precisely excised with evidently a laser or other specialized micro-wave tool that tends to cut only BETWEEN the cells . . . all while one is conscious for however long. Great fun. Especially with one's government insisting nothing's happening, walk on by.
