What choices did the family of Emmett till and their supporters make in exposing the brutality of his murder?

In exposing the brutality of Emmett Till's murder, it forced people from all over the US to see with their own eyes the horrific results of racism. His family insisted on having an open casket, so that the world could see his mangled and disfigured remains of his body as it would be extremely difficult for any American to ignore.

Is there options that you can choose out of?
