Not a surprise to me, Steamboat.
I requested a BLM investigation after being targeted by a BLM law enforcement officer consequent to exposing (and opposing) a hidden BLM agenda. It was necessary to file a complaint through my congressman to get a response.
Without introduction, the responding BLM investigator stepped from his truck and began to take pictures of my property with a camera outfitted with a powerful lens. (Other property owners who had objected to BLM practices were coincidentally subject to complaints for code enforcement and zoning violations.) Curiously, my complaint against attempted intimidation by BLM was met with further intimidation.
Before conducting the interview, the assigned investigator advised me , "You are not going to like the results of this investigation." My interpretation was that the "investigation" was going to be a charade. When I finally received the "results", the report was fragmentary, inconclusive and missing the signature block and signature of the investigator. (It should be mentioned that the BLM investigator was a friend of the BLM law enforcement officer being investigated.)
A comprehensive investigation of BLM would likely expose bad practice and corruption at all levels.
