Do you mean the government that stole their land, indoctrinated their children, decimated their cultures and traditions, put them on reservations from which they couldn’t derive sustenance, and poisoned them with alcohol? That government? American Indians should be as free from federal interference as they are free from federal help. Leave their remaining lands alone, no pipelines, no drilling or fracking by federally subsidized corporations that have so damaged our environment. If the government won’t help them, the least it can do is leave them in peace to use cannabis.
