Roger Hearing is joined by Heather Timmons, Asia correspondent for Quartz and Nancy Marshall-Genzer, reporter for Marketplace. They're talking about the murder of US journalist James Foley by Islamists and ask, following outrage over the sharing of the video of his execution on social media, if there are some things which should be off-limits online.

We hear from Scotland about how independence there could affect the country's buoyant banking sector and Juliana Liu reports from Hong Kong on the big business stories happening in Asia.

Plus, Kickstarter potato salad sensation Zack Brown tells Roger how following the success of his first crowdfunding project his ambition now is to stage a festival - Potatostock - in his home town next month.
