Seymour Hersh - Investigative Journalist

The terrible truth was exposed thanks to the work of investigative journalist Seymour Hersh. He can look back on a lifetime of reporting that has been punctuated by scoops, prizes and plentiful confrontations with the powers that be. Fifty years on from My Lai, are journalists still able to tell the truth to power?
