On April 4th 1968, Martin Luther King was shot dead.
That same night, New York Senator Robert F Kennedy was due to give a speech in Indianapolis, he decided to change his planned speech and break the news. The police had warned him that, as he would be speaking in the heart of an African American ghetto, that they would not be able to guarantee his safety and that on hearing the news, the crowd might riot.
He went ahead anyway.
He wrote brief notes himself on his way to the venue, and delivered the short speech without drafts or prewritten words.
This short speech, possibly one of the greatest speeches ever delivered by any politician, was made while standing on the back of a flatbed truck.
All major US cities experienced riots following Martin Luther King’s assassination, only Indianapolis remained peaceful.
