“He was my little nephew,” she said. “And we miss him. We just want some answers.” Mr. DiCello said Mr. Walker’s sister, Jada Walker, and his mother, Pamela Walker, chose not to watch the footage of the shooting. They asked not to be described and avoided the news about it. They also called on people to respond peacefully to Mr Walker’s murder. “The family doesn’t want any more violence,” Mr Ditchello said. “It had enough violence. The family wants peace, dignity and justice for Jayland.” Before the video was released, the city prepared for protests. On Saturday afternoon, about 100 people gathered in the parking lot of Second Baptist Church, just outside of downtown Akron. Protesters carried signs, one of which read, “JFJ JustificationFor Jayland.” Many of the protesters criticized what they said was unequal treatment by the police. “When some people don’t follow directions, they get handcuffed,” said Hamza Khabir, 41, a Cleveland resident who leads Equality Law Enforcement Reform, an activist group. “When black people do that, they end up getting shot and killed.” David McDay, 78, said he was frustrated by the lack of change over time. “I’ve always been amazed that the same problems happen over and over again,” said Mr. McDay, a retired Goodyear factory worker.
