A friend and good dive buddy just finished a year & 4 months attending classes at St. James Medical School on Bonaire. Therefore, he had a chance to see Bonaire from another perspective, and he told me about a couple of classmates robbed at gunpoint, as it was around the time of year a lot of med. students had gotten their apartment deposits back in anticipation of leaving the island.
In a nutshell, yes, there is more crime than truck thefts, and if you're a resident of the island, that's an issue. But petty theft from trucks is the main crime targeting tourists.
Bonaire is heavily dependent on tourism, especially diving tourism, and a lot of people who come there are part of groups and network with other divers such as via ScubaBoard. Violent crime on a tourist diver could have a serious chilling effect on tourism and thus the economy. Yes, there have been break ins that have affected tourists. Don't seem real common, but it has happened at dive resort rooms in the past.
When I'm in Bonaire a buddy & I walk around at night in the main city with no substantial concerns. Of course, we don't look or act drunk or rich, don't hit on local women and stay out of bars.
You want some scary island stories, do some searching online for a forum where St. Thomas residents who are U.S.-expatriates talk about crime. Or mainland Honduras. For that matter, people have been posting that the guy who used to run a ferry between Roatan and Utila (I think it was) got murdered not too long ago. Hey, who wants to go to Jamaica?
