Baltimore County's Campaign for Liberty has been using email and social media to garner opposition to the bill — attracting the attention of writer and filmmaker David Simon, whose work includes "Show Me a Hero," a miniseries about a housing desegregation battle in Yonkers, N.Y. Simon linked to a post about the Campaign for Liberty on Twitter on Friday and wrote to his 42,500 followers: "Je suis Yonkers," which means "I am Yonkers" in French.
