South Korea's political leadership was in uncharted territory Saturday after the sitting president resisted arrest over a failed martial law decree days before the warrant expires.The South Korean president was impeached and suspended last month after the bungled martial law declaration -- a political move swiftly overturned by parliament -- with a separate warrant later issued for his arrest.
