Ferguson, Missouri, is in the news again. The grand jury ruling on the Michael Brown case has sparked new protests. Unfortunately, they turn violent with protesters setting fire to shops and businesses and attacking police vehicles. The ruling may be unfair, but what's sad and wrong is that in trying to eradicate injustice, the protesters have done injustice to the innocent owners of the burnt shops and businesses. Violence and peace are mutually exclusive. Alone, violence will never solve our problems.
