The correct answer is D) the civil right movement, because the whole world could see the ugly face of racism
The Civil Right movement actually benefited from the Police tactics.
Birmingham police chief Eugene Connor used dogs and fire hoses to discourage civil rights marchers. But instead, what happened was that American people could see the terrible face of racism and the way it oppressed African Americans. When people saw the police reaction to try to suppress the black people right to express themselves through the protest, the civil rights movement gained more adepts.
