Last night, Jon Stewart decided that he couldn’t make jokes because of what had happened in Charleston. Then he spoke eloquently for five minutes about the murders of nine African-Americans attending a Bible study group in their church. He predicted that nothing would change as a result. He contrasted the typical resigned attitude towards the murder of Americans by Americans with our national response to foreign terrorism. We have been at war in the Middle East for more than a decade; we have spent trillions; we have sacrificed thousands of American lives (as well as even more lives of those in other lands): all to keep Americans safe. Why do we do so little to keep Americans safe at home.
