South Korean Law Casts Wide Net, Snaring Satirists In A Hunt For Spies

SUWON, South Korea -- On May 1, 2007, the police locked Kim Myung-soo in a jail cell so small he could spread his arms and touch the facing walls. On one of those walls, a television was showing trains in North and South Korea preparing to cross the border for the first time since the 1950-53 Korean War. The report also noted that South Korea was donating 400,000 tons of rice to North Korea.

South Korea may indict a man who parodied a North Korean propaganda poster if his version is believed to "aid the enemy." The artist inserted his face and a whiskey bottle into the poster.

Mr. Kim was angry about his fate and confused by the reports of North-South conciliation. After all, he had been told his crime was "aiding the enemy" by running a Web site that sold used books deemed pro-North Korean. These included a biography of Karl Marx and "Red Star Over China," an account of the birth of Chinese Communism by the American journalist Edgar Snow.
