North and South Korea conflict - North Korea is blaming South Korea for driving the two "to the brink of war," a day after the North shelled a South Korean island and killed four people. North Korea said the South provoked the shelling of Yeonpyeong Island by holding a military drill off their shared coast in the Yellow Sea. One Korea historian called the situation a manufactured crisis on the part of North Korea.
Now we're hearing from survivors of the attack, who said they were dazed and shocked. We also take a look at Seoul, a metropolis that lives in the gun sights of North Korea, one of the most dangerous states on the planet. The border is just 40 miles (64 kilometers) north of downtown Seoul, and although no strangers to North Korean hostility, Seoul residents see this attack as different. And as the story continues to develop, all eyes are on China, after its neighbor North Korea provoked threats of "enormous retaliation."
'Opt Out' day and the TSA - The controversy over Transportation Security Administration measures may peak Wednesday, one of the nation's busiest travel days every year, as a group is urging air travelers to protest at airports nationwide.

If a large number of people refuse the full body scans, they will have to take a more time-consuming "enhanced" pat-down procedure.
