Another big surprise is Mexico. It seems like every day there's another gory story about a bunch of people disappearing or getting shot in a gang war. But they're the second-highest ranked in North America at #12, behind only Costa Rica.

Israel I think is similar to Costa Rica in that whatever problems Israelis have, they look around at their neighbors and realize how much worse it could be.

Maybe they're ranking themselves so high because they're not in the "bunch of people gorily disappeared."
