Yes, there is crime at home. To me the point is, why would I vacation where there is an amount of crime that I'm uncomfortable with? At home, I know what areas to avoid, not so much on the islands. Look what happened to Jamaica when they failed to get the violence under control. Tourism dropped, people stayed only on the resort if they went at all, and you missed out on the local culture.
I can go any where in the world for an all inclusive, why go some place dangerous?
