Are the Organisers criminally negligent?

This is indeed a great tragedy, Hanging bridge collapses, 22 pupils drown in motivational program training.... and it illustrates once again the "tidak apa" attitudes of those who have been entrusted to do a job, and to ensure the safety of our children. Its hindsight comment unfortunately, but it has to be brought out for public opinion the question; "did the organisers actually went through the "course content" and the sites designated for the program to ensure that every part is in tip top condition (or repairs made) and the routes safe for the children, BEFORE the commencement of the training. I think answers have to be givien in order that the aggrieved parents and relatives know that their children's safety have not been compromised. Lessons will have to be learnt from this needless tragedy
