On this edition of the Sky News Daily podcast with Dermot Murnaghan, we examine the legal and moral issues thrown up by the decision to deport convicted criminals who are foreign nationals.We’re joined by a lawyer as we discuss how human rights work and why, even for the families of such offenders, they rarely trump the need for the state to protect the public.We also speak to the director of Detention Action, who successfully argued some people shouldn't be deported because of issues over mobile phones at immigration detention centres.
