Everyone in his own direction?
They've had plenty of time. They've had equipment, i.e. boat etc.
Without money or ID they were already dead men walking. I suppose they could have tried to maximise their chances of telling their stories to the press, but they could've just told the people on the bus.
I'm unsure of what actually happened in real life, though.

The release of this film brought public attention to Unit 684, and in 2006 the South Korean government released an official report on the unit and the uprising, officially acknowledging its existence for the first time.[4] Brigadier General Nam Dae Yeon said that the 31 Silmido recruits who made up Unit 684 were part of an air force squadron. Seven died in training and 20 were killed in the uprising. The four who survived were executed after a military trial in 1972.[5] Nam stated that documents describing Unit 684's mission no longer exist, but the government has not denied that its mission was to kill Kim Il-sung.[5]
What actually caused the uprising on August 23, 1971, is unclear. The film shows the government deciding that the recruits had to be killed because they knew too much. The recruits find out and revolt. Jonathan Kim, the film's producer, acknowledges that history is unclear at this point.[5]
Six guards survived the Silmido uprising. One of the guards, Yang Dong Su, confirmed that the unit's mission had been to infiltrate North Korea and kill Kim Il-sung. Yang stated that though the film portrays the 31 recruits as death-row inmates, most were petty criminals. Yang stated that "They were the kind who would get into street fights a lot". Yang also gives his version of why the uprising occurred.
They revolted because they felt that they were never going to get the chance to go to North Korea and that they would never be allowed to leave the island. They were in despair.[5]

On May 19, 2010, the Seoul Central District Court ordered that the government pay 273 million won in compensation to the families of 21 members of Unit 684. The court found that "the Silmido agents were not informed of the level of danger involved with their training, and the harshness of the training violated their basic human rights" and also acknowledged the emotional pain the government caused by not officially disclosing the agents’ deaths to family members until 2006.[4]
*just copy from wikipedia, this is the true story, they never come to Seoul, they just make riot in that Island and died there.
THRILLER IS MY FOOD!
