It's important for citizens to participate in the lawmaking process by lobbying for changes they want to see, U.S. Supreme Court Justice Sonia Sotomayor said Tuesday at Emory Law, during an appearance that included a conversation with her former law clerk, Professor Fred Smith Jr. "I believe with all my heart that unless we become engaged in our country and become active participants in making a difference in the world we're in, that we will be nothing but bystanders otherwise, and nobody should live their life being a bystander," she said.
