That is a totally legitimate question. Many should be able to be identified at the BLM corral from the high res pics circulating on the web.
Based on the diversity of "uniforms" (They look fabulous, simply fabulous) it looks like the BLM STASI wolf pack was assembled from a number of sources. Again, those who interact with some of these folks on a local basis should be able to ID their locals who showed up at the Vegas BLM Party.
The Helicopter Cowboys I think are from Utah and likely involved with other BLM actions, like the round up of wild horses.
My biggest question is: Did the BLM hire some mercenaries or did all of their troops belong to a government force?
There is already some stuff kicking around on line about some Special Agent in Charge . . .Something P Love . . . A green beret that was on the Stassi side.
