This would require a backhoe. So, you go over to the nearest BLM center and ask them about their backhoe being out (they typically one and only one). I would imagine they don’t want to provide any comments. If the cows are found with gunshot wounds....it opens up a pretty big mess. Someone will ask about BLM folks with expenditures of ammo, and you’d need a court situation to dig further into this.
In the video where the spetnaz Taz him they are blocking a dump truck and backhoe. Go back and look.
There was mention of a backhoe on a trailer by a protester who was interviewed there. The BLM uses large holes in the ground like this to close a road to all traffic, jeeps etc.
In the first video posted, the taser one, the Bundy supporters can be clearly heard repeatedly asking, “What are the backhoes for?, What are the backhoes for??” The cattle weren’t meant to survive and by extension neither were the Bundy’s.
