Is this even an argument? The people who visited were not protected. So the families should sue the organizer for the big safety issues. They guaranteed safety was top priority. I am sure in a civil lawsuit the organizers will be held responsible for the deaths somehow. The families have every right to ask for money to pay for funerals. Even if they are rich or they got an insurance, because no one who goes to a concert expects to have a risk of dying. You can expect to maybe be dehydrated or get your shoes ruined, but not complete hell.
