What do the roses symbolize to Derek?

Yes definitely I agree with Atticus that according to him it is the court that is the only institution that can serve as an equalizer of men. Hence in the court there is a fair trial without the pressure of social traditions such as racism and influencing the facts. Though he believed that the people may not have been born under equal circumstance but they should be able to get an equal and fair trial in the court. There is a fact that the courts are the great levelers and in there all men are created equal.
