MInd-boggling video of a billowing, high-carbon, high-sulfur cloud from the mountain of petroleum coke - waste from Canadian tar sands shipped from Alberta to Detroit, and the dirtiest potential energy source ever - illegally stored by the Koch Brothers along the Detroit River. Produced by Marathon Refinery but owned by Koch Carbon, the pet-coke piles have for months been producing "fugitive dust" - ie: thick black crud - that blankets the homes of outraged residents and lawmakers; analysis shows the dust contains elevated levels of lead, sulfur, zinc and the likely carcinogenic vanadium. Environmental officials say the Koch Brothers broke the law by not getting a permit for their toxic dump, and they can't guarantee there won't be another "dust event," but not to worry: The Kochs reportedly plan to move the mess to some other poor beleaguered place. We await the day we can exercise our right, not just to free expression and clean air, but to the end of Koch power.

"Is that the petcoke?! Is that the petcoke?! But can we breathe it? Oh my god." - appalled spectator recording the cloud.
