Speakers at the conference said that what people want is to form a powerful and independent special investigation committee for thoroughly probing the truth about the "Sewol" disaster and the humidifier and sterilizer case and punishment of chief culprits.

They contended that the "National Assembly" has to pass a special law for the probe into truth behind social disasters and the building of a safe society.

At the end of the press conference, the participants thrust to the NA a document signed by more than 105 000 in demand of a probe into the truth behind disasters.
