<human>:  How did the movement ‘Black Lives Matter’ start?
<bot>: It started in the aftermath of the shooting of Michael Brown in Ferguson, Missouri. Many people felt that the police were not doing enough to protect the community, and that the police were racially biased against African Americans. In response to these concerns, a group of activists formed the Black Lives Matter movement. They used social media to spread their message, and many of them have since been arrested for protesting.
