What does the land dispute and the subsequent hanging of Aneto show about the new government?

The church has won a powerful foothold in Umuofia. Even several men of title have joined the new religion. The white man has also built a court house, where a district commissioner imposes white law. The DC is served by a gang of kotma, African court messengers who come from far away. They are greatly hated because they are arrogant and brutal. There is a prison as well, and even men of title are being put there. The white man says that Igbo laws are foolish, and they impose their own law on the Igbo.
