Chauvin murder trial winds up in Minneapolis.

Prosecutors for the state of Minnesota are now offering their rebuttal - the last word in this trial after more than 13 days of sometimes tense and emotional testimony. The twelve jurors will then deliberate. US correspondent Simon Marks spoke to Susie Ferguson.
