[Narrator:] No one ever did time
for the killing of the 14-year-old Black boy from Chicago.
But his murder,
and the trial and acquittal of his killers,
sent a powerful message:
If change was going to come,
people would have to put themselves on the line.
Contributors to Civil Rights groups soared.
And 100 days after the death of Emmett Till,
Rosa Parks refused to give up her seat to a white person,
and the Montgomery bus boycott began.
[Mamie Till:] When people saw what had happened to my son,
men stood up who had never stood up before.
People became vocal who had never
vocalized before.
Emmett's death was the opening of the Civil Rights movement.
He was the sacrificial lamb of the movement.
