Chris Daw QC is a high-profile criminal barrister and author of 'Justice on Trial'. He thinks our justice system needs to be scrapped and reformed - from legalising drugs to stop sending offenders to prison.

At the end of a Channel 4 News special week when we have focused on the criminal justice system with the 'Secret Barrister', Krishnan speaks to Chris about why he wants to completely change the way we think about crime and punishment.
