Panorama investigates why black men in the UK are more likely than white men to have force used on them by police and to die in police custody. Reporter Mark Daly follows the family of Kevin Clarke on their search for justice. Mr Clarke repeatedly said, 'I can’t breathe' as he was restrained by police on the ground for 14 minutes during a mental health crisis. He died soon afterwards, his words mirroring those of George Floyd, whose death in the US triggered a global debate on race and policing. The programme also reveals fresh evidence in Scotland’s most high-profile death in custody. Sheku Bayoh died in 2015 after being restrained by up to six officers.
