The Dutch have a strong influence in Aruba because it was originally ruled by them. The native Arubans are very nice and friendly. I do not gamble and always said I worked too hard for my money to throw it away. I, too, never wanted to go there but my husband talked me into it. That was almost 30 years ago. He passed seven years ago and I still go. I am sometimes there by myself but feel perfectly safe. The same people return every year to the small resort condo where I stay and it is very quite and peaceful. The beach and the aqua waters are my favorite. Dining there is an experience from getting a hamburger at McDonald's to an expensive Argentine beef steak at El Gaucho which is to die for. It is safe there and if you look in your paper today and see where someone was shot and killed locally the chances of you seeing that in Aruba are slim to none.
The govenment is run differently there and follows the rules of the Dutch government. It's not that they are lazy, it's a matter of their procedures, rules regarding evidence are different than ours. The only way off the island is by boat or plane so if you are involved in an investigation and you try to leave without permission there is a good chance you will land in jail and they can keep you there until a judge decides whether or not you will be charged. My guess is they kept the rock and ipad until the judge made the decision that there was enough evidence to hold him. That is how they do it. My guess, too, is that LE does not make the decision to send the blood samples off to Holland, the judge does.
Just because their rules and procedures are different than ours does not mean they are lazy. They are anything but, as I have seen those officers standing out in the heat 90 plus with their radar guns on the back roads where the locals tend to speed.
Not so easy to prove guilt when there is no evidence which is pretty much what happened to NH.
Also I have been to many other Caribbean islands and I think Aruba is about the safest. Don't let the casinos bother you because you can avoid them and still have a good time. jmo
