The painting was events of May 1963 in Birmingham, Alabama, when police commissioner Bull Connor employed attack dogs and fire hoses to disperse civil rights demonstrators led by Martin Luther King Jr. You can tell that this was not right and it should of never happened. Anyone should have their own rights. After all we are all one. The art work also has the colors red, white, and blue which I believe represents the flag and peace. This painting has a lot of meaning behind it.
