In this episode of The Global African, we hear from Dr. Carl Hart, neuroscientist at Columbia University, on how the Brazilian government has implemented repressive drug laws that ultimately repeat the same mistakes made in the U.S. ­ In the second half of the show we cover new changes to the Rwandan Constitution that could mean that President Kagame ends up staying on until 2034. What is driving the push for this term extension? The Global African host Bill Fletcher looks at these issues with Dr. Carl Hart, Neuroscientist at Columbia University, and Claude Gatebuke, Co-founder and Executive Director of African Great Lakes Action Network. teleSUR
