Michael Brown shooting: How Ferguson protests spread
A dozen US cities have seen new protests over the decision not to charge a white policeman who shot black teenager Michael Brown in Ferguson, Missouri.
Demonstrations from New York to Seattle were mostly peaceful but rioting broke out in Oakland, California.
There was some unrest in Ferguson itself, with police making 44 arrests, but the town did not see rioting on the scale of Monday night.
BBC News looks at the aftermath of the grand jury's decision.
