To answer you're question about walking around off the resort and crime, yes there is some, and if I was you I wouldn't walk around much at night unless your in the downtown area, even then be careful.
I once was sitting with my girlfriend outside of the Black Hog Saloon, waiting for my dad and little brothers to get down playing in the arcade there, and a truck full of Arubians (most likely drunk), pulled up, and threw a full cup of soda at us (You know, like the size of a large from Taco Bell, McDonalds, etc.). Luckily, it missed us. We had done nothing wrong, we were just sitting there. There had to have been more than 10 of them in the bed of that pickup truck. When they pulled up yelling and acting crazy, we both just got that feeling that something bad was going to happen, and sure enough...
To me, the area's where the Arubians live (Not Downtown, or where the hotels are located) looks like a third world country. Goats, chickens, dogs running around. Children walking on the streets with no shoes, very dirty, and in scraggly clothes. It's just scary and quite sad. Not to mention, I really don't think the true natives there are too found of Americans, I mean let's be honest, who he?
Hope that helps.
