Earlier today, American History tv was live from detroit to look back 50 years. Our guests joined us at a Detroit Free Press room to talk about what happened and why and to answer viewer questions. This is about two hours. You are watching American History tv on cspan3. 50 years ago today, riots erupted in the city of detroit, michigan, sparked by a police raid on an illegal bar known locally as a blind pig. Five days later, 43 people are dead and 7000 have been arrested. President lyndon b. Johnson sent 5000 federal troops. Property damage was estimated at more than 30 million. The affected areas still bear the scars of the riots today. Green spaces mark where a thriving commercial district once stood. There are lingering questions about how far detroit has come addressing the issues that led to the rioting. We are here with the Detroit Free Press. And we are joined by professor Heather Ann Thompson a detroit editor. Ss we will be live for the next two hours taking your calls, tweets,
