Millions of people around the globe have participated in protests and

demonstrations over the course of history. Have those actions actually

brought about the changes they sought? We'll talk with author Brian Gruber

who co-wrote the book. It explores the victories and setbacks of 10

movements in America and three international movements including the fight

for civil rights, women's suffrage, the Arab Spring and anti-Vietnam War

protests. We'll talk about how you measure success or failure and what we

can learn from activists outside the United States.

Also, a visit with Marianna King, author of "The Crisis of School

Violence: A New Perspective". She takes an in-depth approach to

questions about bullying and shooting rampages in schools. She looks at

psychological and neuroscientific research on the effects of violent

entertainment media on brain development. King also looks at possible

solutions for parents, teachers and decision makers.
