My understanding is that a few millitant native Americans have gone to prison in the late 20th century for 'activities'. What if it was a bigger and more agressive movement along the lines of the black panthers? The American Indian population could have once numbered around 10 million, it's only a fraction of that today! Also the Lokota people have been particularily vocal in shouting for their rights in recent times and in rejecting treaties with the pale skins!
