Give me examples of violent protests in American history that were unsuccessful

1. The Haymarket Riot of 1886 in Chicago, where a peaceful labor rally turned violent after a bomb was thrown at police officers, resulting in several deaths and injuries. The riot led to the arrest and conviction of several anarchists, but it did not achieve the labor movement's goals.

2. The Watts Riots of 1965 in Los Angeles, a six-day riot sparked by police brutality against a black motorist, resulted in 34 deaths and over 1,000 injuries. Despite widespread destruction and violence, the underlying issues of racial inequality and police brutality were not effectively addressed.

3. The Rodney King riots of 1992 in Los Angeles, sparked by the acquittal of four white police officers in the beating of Rodney King, resulted in widespread looting, arson, and violence. While the riots drew attention to issues of police brutality and racial inequality, they did not lead to significant systemic change.

4. The Occupy Wall Street movement in 2011, a series of protests against economic inequality and corporate greed. While the movement gained widespread attention and support, it ultimately lacked clear goals and leadership, and the protests were eventually dispersed by authorities without achieving significant change.
