The World in Words 10: free speech special from Singapore, China and the U.S.

With a nod to July 4th, we check in on a quintessential American value: free speech. President Bush says it’s a foreign policy priority. Well, actually, it’s not when it comes to U.S. ally Singapore. We also take a look at a bill in Congress called the Global Online Freedom Act. And we spend some time with a Pakistani-American family living in Phoenix, AZ, who together have written “The American Muslim Teenager’s Handbook.” That and a tribute to George Carlin.
