If the govt does not have the means to imprison the criminals, then there will be more of them out on the street, stealing your cameras.
This is no less true or more true in any one country than another. There are areas in any country where poverty exists with little crime and vice versa--poverty per se does not cause crime. If you go to the "bad part" of any city or town anywhere in the world, you can get robbed. If you go to the "nice part" of town anywhere in the world, you will be safe.
If you're in a big city crowd, anywhere in the world, you might get your pocket picked or your strap cut. No country is any more or less immune.
I've been walking the streets with cameras around my neck in Korea, Japan, the Philippines, Thailand--even in small villages with just a bit of care, I've not been bothered at all or even worried. I've been mugged four total times in the US, as I mentioned, twice within 48 hours in DC.
And there is no government that doesn't have the means and ability to catch petty thieves and put them away--Third World countries are rather better at that than industrialized countries. It's the major crime lords that have the pull to stay on the street, not the petty thieves. And come to think of it, major crime lords manage to stay out of jail in industrialized countries just as easily as Third World countries.
