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.
Photos of those destructive actions should be made.
I think an examination of the cows in the grave will reveal that they didn’t die a normal death....and thus a report to the county sheriff will open up a grand jury episode. Some guy....really opened up a can of worms here. No fed protection for shooting cows....you get taken to the grand jury and have to explain your episode. Even if you were just the back hoe operator....you basically were part of some conspiracy. All of this leads back to paying the rancher for his cows....if there are ten....figure $20,000, and probably another $5k to $10k for damages. The BLM won’t pay for that stuff....it’ll come out of your own pocket. So I think I’d start pointing fingers quickly and note which BLM guy did the killing. If I were the guy....I’d pack up and leave the state.
