The letter from Mr. Robertson denounces the recent takeover of the Bureau of Indian Affairs building in Washington and expresses disappointment in the actions of the federal government. He questions how he can teach democracy to his students without feeling like a hypocrite. He poses a hypothetical scenario of his students taking over the post office and asks for guarantees of amnesty, transportation, and payment during the protest. The Speaker responds by emphasizing the importance of patience and perseverance in the democratic process and encourages Mr. Robertson to promote good citizenship and understanding.
