Demand an End to Racism relating to the Judicial System!

My brother got sentenced to 20 years, his friend 40 years, and his other friend 12 over a crime in which they were mentally impaired. My brother is an Arab Muslim and his friends are bosinian muslims. We suspect that his judge was in fact a racist. It is not fair. We want change and impartiality. I believe that if we all can rise against the immoral chunk of judges, we could possibly get justice for our family members. Please help.
