Answer:
It was used to discourage protesters: violence against the boycott leader, arrest of the boycott leader, appeal of a federal court decision that supports the boycott.
Explanation:
The black population of Montgomery decided to boycott the city buses, ending its boycott only when the law of segregation of races in public transport was revoked. The boycott would financially cripple the bus company, attract tens of thousands of Protestants to demonstrations, present to the country a young charismatic leader named Martin Luther King Jr. and would spark a movement that would spread to Little Rock, Greensboro, Raleigh, Birmingham and, for end, to Congress. Parks would become a heroine, endowed with the Presidential Medal of Freedom, and a shining example of how a single act of challenge can change the world.
But that's just part of the story. In response to the boycott, white opponents decided that they should stop the boycott and so caused acts of violence against the boycott leader, the arrest of the boycott leader, and appeals to stop a federal court decision that supports the boycott.
