The DuPage Unitarian Universalist Church in Naperville will hold a panel discussion tonight on gun violence in the wake of a sniper’s killing of five police officers and injuring seven more in Dallas Thursday night.
The Rev. Tom Capo said his congregation has committed itself to the issue of racial injustice, particularly in the criminal justice system. Part of that commitment has been to forge alliances with many of the African-American churches across the Chicago area to develop a greater sense of community and to enact plans that can address issues such as gun violence and racial injustice, he said.
“This is something we have been working on for some time to have people sit down together and work on our relationships,” Capo said. “We know this issue is a problem… we know we all have to work together on this.”
Naperville Police Chief Robert Marshall will be among those participating in the panel discussion, which begins at 7:20 p.m. at the church, 1828 Old Naperville Road.
