A former building engineer for Focus on the Family, the conservative religious organization, Chinn was present during two violent incidents at its facilities. As a result, Chinn began tracking deadly force incidents at houses of worship; he told Colorado Matters that there have been more than 1,600 such cases since 1999.
Chinn has formed a non-profit, Faith Based Security Network. Its goal is to help houses of worship prepare for and prevent acts of violence.
