"Cracking the Wire" is a comprehensive account of the BLM movement, which emerged in response to the acquittal of Trayvon Martin's killer in 2013. The book explores the movement's roots in the long history of Black liberation struggles, its key demands and strategies, and its impact on American society. Davis, a renowned scholar and activist, draws on her own experiences as a Black woman and a veteran of the Civil Rights Movement to provide a nuanced understanding of the BLM movement.
