Final answer:
The Black Lives Matter movement, which began in 2013 after George Zimmerman's acquittal, is a protest movement against police brutality and racially motivated violence against Black individuals. It is true that the movement arose from incidents such as the killing of young Black men by police. BLM is a decentralized, grassroots movement that leverages social media for organization and advocacy.
Step-by-step explanation:
The movement "Black Lives Matter" (BLM) indeed arose primarily as a protest to the killing of young Black men by police officers and the deaths of Black individuals in police custody. The statement that the BLM movement began as a protest to a series of killings in which young Black men were shot by police or died in police custody is true. The organization was founded in 2013 after the acquittal of George Zimmerman and has since become a core part of the movement protesting against police violence, exemplified by the killings of George Floyd, Breonna Taylor, and other Black victims. BLM seeks to address systemic racism and introduce new laws to hold police officers accountable for their actions. The movement also underscores the importance of community-driven law enforcement and the redistribution of police department funding towards more holistic approaches. BLM's mission is to eradicate white supremacy and to intervene in violence inflicted on Black communities by the state and vigilantes. It is a decentralized, grassroots movement that uses social media to organize, unlike the 1950s and 1960s civil rights movements, which were organized through African American churches and political institutions.
