The Killing of law enforcement officers in Dallas was the latest gun tragedy in the extraordinary life of the city’s police chief David Brown.
Mr Brown, 55, lost both his brother, and first police partner, to gun violence.
Most painfully of all, six years ago, his own son shot dead a policeman and was then killed himself by other officers.
Mr Brown, who is black, grew up in a rough neighbourhood in South Dallas and describes himself as an “inner city kid”.
Having seen firsthand the ravages of the crack cocaine epidemic in the early 1980s he became passionate about joining the police force.
Dallas police chief says his profession is ‘heartbroken’ and ‘hurting’. An estimated 990 people in the US were shot and killed by police in 2015 alone. Their deaths fuelled the #BlackLivesMatter movement.
In 1988 his first partner, Officer Walter Williams, was investigating a burglary when he was ambushed and fatally shot in the head.
Three years later his younger brother Kelvin was also shot in the head and killed by drug dealers. Mr Brown was devastated by the tragedies but forged on, spending most of the 1990s as a SWAT officer.
In 2010 he was made head of the Dallas Police Department and its 3,600 officers. Weeks later, on Father’s Day, a gunman randomly killed a young father who was driving his family in a car.
A police officer rushed to the scene and was also shot and killed.
More police arrived and opened fire, fatally hitting the gunman with 12 bullets.
Incredibly, they then discovered the dead shooter was 27-year-old David Brown Jr, the chief’s son.
