Months after Attorney General Eric Holder launched an investigation of Ferguson Police Department in the wake of Michael Brown’s death, the Department of Justice released a 102-page report detailing systemic race discrimination and abuses of power in the embattled city. But despite the DOJ’s damning findings, the city’s mayor remains unconvinced that widespread problems exist.

“What they’ve shown is that it has happened. Now, how often has that happened? I don’t know. Their assertion is it happens regularly. Based on what? I’m not sure yet,” said Mayor James Knowles III, during an interview Friday. “Do they have a statistic that tells me that they’ve examined every arrest that we’ve made for the past four years and that half, or all, or 10 percent, or 5 percent are unconstitutional or without cause? They do not have that. They have not examined at that level that I know of at this point.”

He also maintains that there is “no proof” of gross civil rights violations.
