The Rev. Jim Wallis is sending a powerful “wake-up call” to white Christians who are refusing to fight back against a “racialized police system.”

Wallis and other faith leaders and social activistswere recently arrested during another slew of peaceful protests in Ferguson, Missouri.

Ferguson has been the site of many marches, rallies and demonstrations after 18-year-old Michael Brown was fatally shot multiple times in August by white police officer Darren Wilson, despite Brown allegedly having his arms up in surrender prior to several shots being fired.
