On BH this week, we have the latest on the devastating earthquake in Chile, and the fears for a resulting tsunami in the Pacific Ocean. We hear from Chile, New Zealand and Japan. Also, following criticism of Birmingham social services in the tragic case of Khyra Ishaq, we speak to a frontline social worker about the dilemmas of the job. Our reporter Terry Stiastny delves into the world of 19th century anarchist terrorism and asks; why are the names of those who helped the security services still kept secret? And in the week that it was announced that General Motors will no longer be making the Humvee, we take one out for a spin. The Sunday papers were reviewed by comedian Bridget Christie, chair of the Arts Council England Dame Liz Forgan and author Michael Dobbs.
