Tinker siblings draw parallels of student protests from the 1960s to present

In 1965, John and Mary Beth Tinker protested the Vietnam War by wearing black arm bands to school. The incident led to a landmark Supreme Court decision that guaranteed free speech rights for public school students. The Tinkers reflect on this history and present day threats to the First Amendment. Later, a new play from playwright Megan Gogerty works through her complicated feelings about her father and family's history as a sixth generation Iowan.
