'Mums Make Porn' - Channel 4 defend porn movie freely available via website

Let's talk about porn. Have you been watching the Channel Four series, Mums Make Porn? The three part series ended this week and the explicit porn film made by the mums, called Four Play, has now been posted online by Channel Four. It's free to view, but viewers have to prove they're over 18 with a credit card, driving licence or mobile phone. Is this what Channel Four should be doing? It describes itself as: "A publicly-owned and commercially-funded UK public service broadcaster, with a statutory remit to deliver high-quality, innovative, alternative content that challenges the status quo." Stephen got the views of commentator Emma Woolf and Malachi O'Doherty.
