It's a big place. Maybe the Coast Guard could have done a better job in this instance. But to go after them for millions of dollars reduces her to a golddigger and reduces her lost family members to items on a ledger sheet. In the real world people get sick and die. Not every death or injury entitles family members to millions of dollars in cash from the deepest pockets they can find.
Lawsuits are one of the primary reason why health care is so expensive.
In most cases, mediation is more ethical, honorable and cost-effective than a lawsuite as a means of solving a dispute. The death penalty is a highly controversial issue, with people concerned about crime and victim's rights on side and people concerned with its severity and permanence on the other side. We certainly don't advocate any position here, but we would advocate people being aware of the facts and the positions of both sides of the issue. Neither the relatives of murder victims nor opponents of the death penalty should be demonized. Nobody weighs in on this issue for purely personal or selfish reasons.
