I think this is probably my first SB post, although I browse the site constantly. Let me say that I did not read this entire thread (I don't have an extra 3 days to do that) but I do have an experience to relate that I haven't seen referred to anywhere in the thread.
I've only been to Bonaire once but loved it and intend to go back. I had heard all the stories about crime and being cautious. We were traveling with people who had been frequent visitors to the island, so it wasn't so much of a concern for us as it might have been for the first-timer.
I do have a point: everything I/we heard about crime on Bonaire pre-trip usually came back to "well, the island has a poverty problem etc. etc." - and every story put the blame for the crime issue squarely on people who live there. As we were coming back from a snorkeling jaunt at Red Slave (on one of the days I couldn't dive) I happened to notice a truck pull up next to ours. Since our vehicle was the only other one there it wasn't difficult to track what happened.
Two people got out, both geared up to get in the water. One guy started putting his tanks on, but the other very deliberately looked in, walked around and tried to get into our truck. I watched it all happen. By this time we were fairly close to the shore, and there was a real look of surprise when he looked out to sea and saw us approaching. They quickly got into the water and started their dive - I know they wanted to get away from an uncomfortable situation before we could get out of the water.
End to my point: while I obviously have no way of knowing where they were from, my feeling is that they were tourist divers, just like the rest of us. Curious that most of us never stop to think that there are likely divers, who, knowing that Bonaire has a 'rep', will take advantage of that 'rep' and of fellow divers.
Just sayin...
