Vivid protests are routine in the South Korean capital. But lately, speculation over a potential visit from Kim Jong-Un has sparked debate over how far to let protests go if Kim comes to Seoul. People there often air some strong views.>> Once Kim steps on our land, he will be captured and no one can take responsibility for what will happen afterwards.
>> Views like that are going to make it hard for the South's President Moon Jae-in to get the summit he wants, full of imagery of a united Korean Peninsula. It's a different atmosphere to the Singapore summit with US President Donald Trump in June. There, the supreme leader even went out for a night time stroll.
But Singapore is a tightly controlled city, and while Seoul official say it's unlikely Kim will visit by the end of 2018, protests present a security challenge for the south leader, says Reuters' Josh Smith in Seoul.>> Moon Jae-in treads a fine line between trying to create a welcoming atmosphere for Kim Jong-un, and at the same time, allowing for free speech and potentially the many protesters who say that they plan to come out and protest Kim's visit here in South Korea.
Already, even just the prospect of Kim coming to South Korea has sparked debate in the media and among some protesters who say that the government should not go out of its way to provide a false welcoming atmosphere for Kim. Even if it means potentially overshadowing some of the more happy, feel good optics that Moon might want.
>> Kim's visit would be the first by a North Korean leader to the South. So security forces on both sides will be treading unknown ground. However at its G20 Summit in 2010, South Korea mobilized 50,000 security forces. Police sources say Seoul is likely to declare the highest level of emergency preparedness for a Kim visit.
That means all five of the city's thousand strong crowd control divisions would roll out and tens of thousands of officers would be called up from other agencies including the military.
