TOPSHOT-US-CRIME-POLICE-RACE-UNREST

TOPSHOT - Michael Brown's mother Leslie McSpadden (L) and other protesters react after hearing the grand jury decision in the fatal shooting of her son in Ferguson, Missouri, on November 24, 2014. Violent protests and looting erupted in the US town of Ferguson after a grand jury chose not to press charges against a white officer who shot dead the black teen. US President Barack Obama and the family of late 18-year-old Michael Brown separately appealed for calm after a prosecutor said a grand jury had found the policeman acted in self-defense.
