Attack on US Ambassador Renews Scrutiny of Controversial Korean Security Law

U.S. Ambassador to South Korea Mark Lippert is out of the hospital and recovering a week after he was slashed across the face and wrist by a knife-wielding assailant. Now authorities say the attacker might have also violated a decades old anti-Communism law. But, some rights groups say the attack shows how the law mainly limits freedom of speech without improving public safety. Jason Strother reports from Seoul.
