The recent death of a man in police custody sparked riots in the US city of Baltimore. The exact circumstances of Freddie Grey's death are still to be determined.

This is under a month after the death was reported of Walter Scott who was shot in the back 8 times by police in South Carolina in early April.

However it is a useful reminder for G and P students of Unit 3C that there are still numerous racial problems in the US, despite the progress that has been made since the civil rights movement of the 1960s.
