Found nowhere else in the world? I agree that this particular situation and approach to dealing with it is pretty unique, at least to the degree it exists in Bonaire, but I'm concerned that this statement...
...an accepted level of criminal behavior found nowhere else in the world...
...gives the impression (though not literally stated) that Bonaire has the highest level of criminal behavior in the world. I'm not usually a nuance Nazi, and I don't want to be paranoid about this, so please take the criticism in that light.
The petty theft from rental trucks is generally:
1.) Non-confrontational (you aren't confronted face-to-face by the criminal, unlike a mugging or home invasion).
2.) Non-violent.
3.) Minor valuables - not like a home burglary where they got your t.v., computer, the wife's jewelry collection, etc...
4.) Can be avoided by a fairly simple of set of well-known, easy-to-follow precautions.
I think the safety practices in Bonaire are particularly irksome to some because they're not what we're used to at home. For most of us, I think, you lock your doors at home when you're out (and many of us usually lock them when we're home), your car doors when you're out (and at home, if not parking in a private enclosed garage), your car may have a car alarm, your home may have a burglar alarm, and some people choose to own a gun and/or a sizable dog for perceived added security (without veering off into the gun ownership debate). Some women carry pepper spray on their persons in some public areas. Many areas have neighborhood watch programs.
It's worth remembering that some of our ordinary, everyday security measures, which we think little about, would be alarming to a stranger who'd never needed to do those things.

P.S.: At my wife's college orientation a few years back, one of the speakers was the head of security, and he spoke about not leaving obvious valuables in view inside your car where they could trigger a smash & grab, and told students about these campus phones placed here & there where someone could call for help. When I went to college years ago, I learned you could go to a room & knock at a guys' dorm, but you didn't get past the front desk at the female dorm unless they called the room and a resident cleared you to come up. While these measures may be good things, if we assume they arose to meet a need, then how many vandals, thieves and would be rapists must there be right here at home?
