It appears that Shell's recent loss of their Noble Kulluk deep sea drilling rig and the endangering of the marine community off Sitkalidak Island, Alaska, came about because Shell wanted to avoid paying state taxes. Rachel Maddow covers this for MSNBC here. When you consider Shell's massive profits in 2011 and their protests against the regulatory system, this is pretty outrageous!
One positive which I hope will come out of this, is the increased political scrutiny and public focus may well, I hope lead to a ban on arctic drilling. I may well be dreaming, with the estimated motherlode of fossil fuels under the arctic but one can hope.
