CNN —  

In his six years as police chief, David Brown has endured profound tragedy – in many different ways.

On Thursday night, a sniper gunned down four of his Dallas police officers and killed another officer.

Shortly after he earned the rank of chief, Brown lost his own son in a police-related shooting – after his son shot and killed an officer.

As Brown prepares for several police funerals, he faces yet another grueling challenge: trying to lead a grieving department amid anti-police tensions across the country.

“We’re hurting. Our profession is hurting. Dallas officers are hurting. We are heartbroken,” Brown said. “There are no words to describe the atrocity that occurred to our city. All I know is this: This must stop, this divisiveness between our police and our citizens.”

Tough beginnings

The sniper who killed five officers Thursday night was bent on killing white officers, Brown said.
