What gets me is that he claimed it was a "last resort", that he had tried to do everything he could prior to his actions. BS, he could have found legal council and thrown a wrench in the spokes with a law suit. It was in no way, "a last resort". I don't doubt that there may have been parcels of land being auctioned off that had yet to even be properly evaluated (it happens all day long when SUWA is forcing "wilderness quality" land down the BLM's throat and threatening lawsuits if they don't get their way, despite some land not meeting proper 'wilderness' requirements), so we can see that tactic goes both ways.
I think Tim had some valid points (minus the whole global warming comment) to want to disrupt the illegal auctioning of land that had yet to be investigated/evaluated, but the way he went about it was stupid. He had every right to protest, speak out against what was happening, throw down a lawsuit or two; but instead caused a massive ripple effect that hit Utah economy with loss of jobs, loss of lease money, possibly loss of funds for Utah schools - if on SITLA lands.
