During the past 10 days on Bonaire there was a murder, a carjacking, armed robberies at a supermarket and a convenience store, burglaries from at least two residences, and thefts reported from several vehicles (including Susan Porter's as mentioned previously.) I imagine that the victims in each incident probably "felt safe" right up to the point where they weren't.
One of the reason thieves steal items from unattended dive trucks is because groups like yours leave things like coolers and cameras behind. This kind of behavior contributes to the problem.
At the conclusion of our upcoming 3 week trip we'll have spent 25 weeks on the island spread over 17+ years. While we still enjoy the island we certainly don't "feel safe" there anymore. Crime per capita is significantly lower (by a factor of 3 to 4 times) in our home city of 300,000+ people than it is on tiny Bonaire. We have no qualms or problems leaving our US home or vehicles unattended for several weeks while on vacation. We had been contemplating purchasing vacation property on Bonaire with possibility of enjoying early retirement there in a few years. But not anymore. We'd be crazy to leave an unattended vacation home full of furnishings, appliances, electronics, dive gear and other valuables.
