After a week of violent demonstrations in Venezuela and Ukraine, we hear from the capital Caracas on the everyday effects of economic chaos and shortages. We've got a special report from Colorado on the problems of selling marijuana, legally, when the US federal government doesn't approve. Also, the EU Trade Commissioner Karel de Gucht speaks out about 'that' trade deal, which sparked the current unrest in Ukraine. And we hear from the man who wants to publish the entire contents of English Wikipedia, in book form. And ABC's Peter Ryan talks us through the Australian-hosted meeting of the finance ministers and central bank governors for the G20 countries from Sydney.
