(CNN) – Alex Stone knew he had no other choice.
The police officer in Clatskanie, Oregon, filed a formal complaint when he allegedly heard the city’s police chief making racist comments.
“I had to do this,” he told CNN affiliate KOIN, but he said the aftermath hasn’t been easy.
“I’ve received death threats, a tire flattened with a nail on my driveway,” he said. “My kids, they’re afraid to go outside.”
Stone’s complaint, filed along with a complaint from another officer over the summer, alleges that Clatskanie’s then-police chief, Marvin Hoover, compared African-Americans to monkeys, made monkey sounds and sang “Dixie” while being debriefed on the arrest of a woman who had said she was discriminated against.
