For a lawyer to do less than his utmost is, I strongly feel, a betrayal of his client. Though in criminal trials one tends to focus on the defense attorney and his client the accused, the prosecutor is also a lawyer, and he too has a client: the People. And the People are equally entitled to their day in court, to a fair and impartial trial, and to justice.
I think it's hard for an outsider to capture the flavor of a community and all its nuances, so ultimately Haitian-Americans need to start sharing intimate accounts of their stories.
