He first came to widespread notoriety in 1990, when the Alberta government sought to dam the Oldman River, which would have flooded Peigan burial grounds. Born With A Tooth led the Blackfoot warrior society in diverting the river away from the dam.
On August 2 of that year, a heavily-armed Royal Canadian Mounted Police contingent arrived, and shots were fired. Born With A Tooth was arrested and charged with endangering lives and assaulting eighty officers. He was convicted and spent three years in prison.
