The purpose of this thesis is to understand Twitter users’ reactions and their discussions on race after the shooting death of Stephon Clark. The study examines the #BlackLivesMatter, #BlueLivesMatter, and #StephonClark hashtags in the six weeks following the killing of Clark. The data yielded 513 tweets that included a variation of all three hashtags, while only 29 tweets were found including the #BlueLivesMatter hashtag. Taking a grounded theory approach, the study utilizes content analysis to code the Twitter data. The results of the data were reflective of the Black Lives Matter movement’s narrative to stop anti-Black racism and end the police-involved killings of unarmed Black men and women. Through the examination of the hashtags, the study demonstrates how Twitter may be a powerful tool used by social movements in their fight to address social issues.
