It can be both.

But to your point, when some overconfident dudebro splatters himself all over the flats, we the people have to pay for the cops to show up, the medics and the ambulance even if the idiot is obviously dogfood, the body recovery, the coroner and the postmortem, and all the associated bureaucracy.

And someone will still sue because the Park Service didn't prevent the moron from killing himself. You can sue for literally anything in the US.
