US police killings: What role does prejudice play?

11 police officers were shot in Dallas by at least two snipers, while five of them were confirmed dead.




This week's fatal shootings by police in the US have restarted national outrage about the treatment of African Americans.

And highlighted once more, the racial disparities in America's criminal justice system.

Alton Sterling was pinned to the ground and shot at close range by police in Louisiana on Tuesday.

A day later in Minnesota, Philando Castile was shot by police in his car, with his girlfriend and her daughter in the backseat.

That was followed by targeted shootings on police officers at a rally against police brutality in Dallas, on Thursday night.

One of the suspects said he was upset about the recent police shootings and wanted to kill white police officers.
