A proposed ballot measure designed to limit the involvement of Columbus police in response to mental health crises and other nonviolent incidents first began to take shape more than seven months ago, according to Chana Wiley of the Columbus Safety Collective (CSC), though its roots stretch back to the January 2017 passing of Wiley’s brother, Jaron Thomas, who died in police custody after he called 911 while in the midst of a mental health crisis and was restrained and beaten by the responding officers, Wiley said.
