Phillips vs. Neidichs

I was very confused when reading Christopher Phillips "Necessary Fictions: Warren Neidichs Early American Cover-ups". We all know that we do not know all the facts about what the Americans did to take Indians off their lands and move them onto reservations, and thats what Phillips tells us. Looking at the pictures from Warren Neidichs you feel a different sense of what really went on. Normally in history books we see pictures of Native Americans looking focused or sometimes sad/depressed. Never did I ever see a picture of Americans moving them out off of their land by blind-folding them and threatening to kill them. I wasn't really sure what else to get from the reading.
