The net is closing in on a billion-dollar cartel, according to the US government. The Kinahan's are an "organised crime group" accused of being involved in drug smuggling, money laundering, and murder. Now US officials have offered a $5 million reward for information leading to the arrest of the gang leaders. The Kinahan’s have long denied having any involvement in organised crime. On the Sky News Daily podcast, Leah Boleto explores the murky activities of Ireland’s billion-dollar drug cartel with our Ireland correspondent, Stephen Murphy, and investigative journalist and author Nicola Tallant. Plus, former Lord Mayor of Dublin, Nial Ring, and former Gardi officer turned security consultant, Sheelagh Brady, on the impact drugs have had in Dublin.
