I interrupt this Korean Adventure to ask a question....

What is going on here???






I stumbled across a protest this evening at the AK plaza south of Seoul, South Korea.  There were hundreds of women wearing white shirts carrying signs and chanting.  A woman spoke, followed by the man in the picture.  Police escorted them into the plaza outdoor courtyard then left.  It was very peaceful.  No news reporters anywhere.  I have no idea what it was all about and would really like to know.
