The president of Roanoke’s NAACP chapter is inviting the entire community to a prayer vigil tomorrow for the 5 slain police officers and two African-American men shot to death earlier in the week. Brenda Hale condemns what happened in Dallas last night. Hale also claims the number of African-American men killed by law enforcement officers has risen in recent years. Tomorrow’s 4-pm prayer vigil is at the Martin Luther King Memorial on Henry Street.
