DALLAS — Behind candles and lights dimmed to near darkness, their faces flashed across the screen. A bootleg CD salesman in Louisiana, a cafeteria worker in Minnesota, a 17-year-old in Florida. Then the face of a police officer, and a second, a third, a fourth and a fifth.

It wasn't necessary for the pastor of The Potter's House megachurch in Dallas to identify the dead projected on a screen behind him. All the faces with light skin were officers. All the faces with dark skin were citizens killed by police.

On Sunday at 11 a.m., which the Rev. Martin Luther King Jr. once called the most segregated hour in America, the black-majority congregation of The Potter's House took time to reflect on a wrenching, tumultuous week of race-related violence in America.

“These are trying times in our nation, but we believe that God can do the impossible,” said Associate Pastor Onterio Green, pacing the vast stage at the front of the church. “Halle-lujah! Halle-lujah! Halle-lu-jah!”

The week had begun with the shooting deaths of two black men at the hands of police in suburban St. Paul, Minn., and Baton Rouge, La. Then, on Thursday night, a Black Lives Matter march in Dallas ended when a gunman disrupted the peaceful protest by shooting 14 people, 12 of them police officers. Five officers were killed. Seven others and two civilians are expected to survive, making this city the locus of the nation's continuing conversation with itself on race, discrimination and justice.

“We are ground zero today,” said Texas state Sen. Royce West.

West spoke from the stage on Sunday, joined by a dozen others, including family members of people killed by police and police officers themselves, who pleaded for patience and understanding. “I wasn't born a robot,” said Dallas Police Department Cpl. Justin Brandt. “We are human.”

Sometimes, the reception in church to the police was icy. After all, the protest on Thursday was meant to bring attention to incidents of police brutality, and some of the marchers were in the pews on Sunday.

When Brandt suggested that the solution to racial tension was giving the police more resources, including money for training, the room was silent.

Some protesters, including James Ali-El, 36, found the presentation in church to be more show than substantive dialogue.

“They're missing the whole point of what's really going on,” said Ali-El, who said members of his family are current and former members of the Los Angeles Police Department. “It's camouflage (to) shut down the black community by coming out here and saying, ‘We have to have sympathy for the police officers.'

“Of course we have sympathy for the officers. But it's convenient. Now they want restraint, now that it's them (who are) hurt.”

Frustration with the police sometimes boiled over during the on-stage dialogue. Potter's House Pastor T.D. Jakes complained that police officers never truly face justice.

“They're always exonerated,” Jakes said.

Jakes then introduced a series of women whose loved ones were killed by police. Saundra Sterling said her nephew, Alton, was like a son to her, and she worried about his decision to return to selling bootleg CDs in Baton Rouge. He was killed on Tuesday by police. “He suffered, he suffered,” Sterling said.

Diamond Reynolds watched her boyfriend, Philando Castile, die in front of her after he was shot several times by St. Anthony, Minn., Officer Jeronimo Yanez on Wednesday. “The officer was scared, I heard it in his voice,” said Reynolds, who live-streamed Castile's final moments on Facebook. “It clicked to me. This is much bigger than myself.”

Jakes asked her what she wonders about when she thinks about that day. “If I could change anything, it was never to take that route,” Reynolds said, her voice breaking. “None of this would have happened.”

Finally on stage was Dallas County Sheriff's Lt. Steven Gentry, who has had a troubled history with his own department. He was fired for filming female inmates in the shower but reinstated due to a technicality. Gentry said he was left at a police station by his birth mother and brought home by a sympathetic police officer, whom he regards as his father. On Thursday, he saw one of his friends and fellow police officers die in front of him.

“Whether you like police or you don't, whether you've had bad interactions with us,” Gentry said, “we're not over you, we're with you.”
