Sean Fletcher and Holly Hamilton host. This episode, the home secretary told police leaders to 'ramp up' the use of stop-and-search powers to prevent more knife attacks. Critics say the practice disproportionately targets those from ethnic minorities, and can leave people feeling victimised. We ask if the police need to get tougher to reduce crime. Also, after world leaders met in Paris to discuss giving poorer countries access to hundreds of billions of dollars to tackle climate change, we discuss if emerging economies can afford to go green. And the plumber working for free to help the elderly and disabled.
