Hey, I haven't been shedding any tears for them. They did something stupid and it cost them dearly. They're lucky they didn't get shot.
On the other hand, maybe they're paleontologists or members of some other group with a reasonably valid reason to go into that area. I'm certainly not going to condemn them when I don't know.
What's fairly clear, though, is that they made a stupid mistake and wound up across the border. I don't imagine they'll do that again.
