Yet, strangely, the convicted felon I was on my way to meet wasn’t a polluter. On the contrary, Tennie White, who was prosecuted by a joint team made up of attorneys from the Environmental Protection Agency and the environmental crimes division of the Justice Department, had spent her professional life exposing contamination. She was an environmental lab owner who was particularly vocal about protecting poor African-American communities. Before she was charged and prosecuted, White had spent much of her time volunteering for an organization she had co-founded to help these Mississippians contend with pollution.
