It's a fair cop is a Radio 4 series broadcast in the UK and available on iPlayer. It's a comedy, but is essentially a former police officer talking an audience through situations he has encountered and asking what their decisions would have been. The previous episode was about when arrests are made and when they are not, but this week's episode is about Reasonable Force and how UK police work with UK law. It's not revelatory or ground breaking, but it is interesting funny and well worth a listen if you're so inclined It's a Fair Cop - Available now - BBC Radio 4
