The "Black Bloc" is a tactic used by some protesters, particularly during demonstrations. Participants typically wear all black clothing, masks, and helmets to conceal their identities. This approach is often employed to create a sense of unity and anonymity among activists, allowing them to express dissent more freely. The Black Bloc is often associated with various social movements, including anti-globalization and anarchist groups. While some participants engage in peaceful protest, others may resort to property damage or confrontations with law enforcement. This duality has led to significant debate about the effectiveness and ethics of the Black Bloc tactic in activism.
