By Brenda Norrell Censored News
Greg Grey Cloud, Crow Creek Lakota and co-founder of Wica Agli on Rosebud in South Dakota, was free last night after being jailed for sounding out in the US Senate the song of the people whose water and land is threatened by the dirty Keystone XL pipeline. The Keystone XL pipeline vote failed in the US Senate yesterday, after being passed in the US House.
Grey Cloud continued singing as he was knocked to the floor and against the wall and handcuffed with zip-ties. Read article and watch videos: http://bsnorrell.blogspot.com/2014/11/greg-grey-cloud-free-after-lakota-song.html
