Generally it's hard to pre-emptively sue to prevent the government killing you -- even though in the US the Constitution requires due process before a person can be deprived of "life, liberty, or property" -- because most ways the government has of killing you (guns, bombs, etc.) happen very quickly. In this case the mechanism by which the government is alleged to be killing people is slow-acting enough that the people who claim they will be harmed have time to file a lawsuit.
