OK, we have sanctuary cities. As I understand it, they are cities where immigration laws are not enforced. Hey, let's play with that. Lets let cities decide what laws are not going to be enforced. Here in Colorado - Denver can be (is?) a sanctuary city. Aurora can be an assault city - go beat someone up. Broomfield can be a robbery city. Go north on Wadsworth and steal something. Vegas already has gambling.
Just think about it - find the city that caters to your favorite illegal activity and go have fun!
