Lets say you built and own a building. It collapses and almost 400 people die (the figure is still being revised). As a good citizen, do you hand yourself in and take the consequences which will at the very least be life behind bars with a bunch of crazies. Remember, nobody will have any sympathy for you, least of which your prison mates - you are a murderer in the eyes of most people.
