I also get real upset when resucers loose their own lives trying to save the people that knowingly take risks like this.
I do agree with your suggestions, maybe that already happens, I do not know.
From all of what I've heard in this non-stop coverage is NO. They go on their merry way and taxpayers foot the bill for their screw ups.
That 'may' have been okay in 1940 when a rescue was impossible due to lack of technology (like no Helicopters), but not in today's world.
What they did was irresponsible.
IIRC Oregon and Montana have laws that allow rescuees to be billed for rescue efforts if said rescuees do something really, really dumb (like in this case).
I suppose they could bill the estates of these new Darwin Award recipients, but I think it would be bad form.
