The people are understandably angry. None of us likes to be publicly called out for our transgressions. The people’s response is also interesting. They invoke the voice of the people, and how they have chosen their lawyers and their laws. This selection by the voice of the people was the very mechanism that Mosiah had suggested would be most effective. Amulek had appealed to King Mosiah, and so, therefore, do the people. The difference is that Amulek had referenced the caution Mosiah gave about when the people would choose evil over good. By saying that their laws were just, the people are suggesting that they are also good, and that they, therefore, have chosen good rather than evil.
Amulek clarifies. He does not dispute that the law is good. He does not dispute that selecting the lawyers by the voice of the people can be good. Amulek declares that the problem is not in the laws, but in the actual people who hold important positions. The voice of the people had chosen unrighteous people.
