In 1919, in the aftermath of serious racial violence, two teen boys were put on trial for murder. The victim was white; the teens were Black.
Their murder trial demonstrates how badly the legal system failed Black Chicagoans in the aftermath of the riots. In that case, those failures were not an accident. Government officials, judges, and jurors willfully ignored (and sometimes created) problems of law and facts in order to win convictions of the two teens.
