"But if my city decides that the illegals are not a problem and that the businesses are crucial to our economy then we should be allowed to ignore them."
I guess you are in support of breaking the law. I thought if you didn't like a law you were supposed to change it. Why bother changing laws you view as unjust; if enough people break it, then the law is invalid. Is this what you condone? Isn't this anarchy?
No, but law enforcement resources are finite, not unlimited. We could spend 100% of the city police budget on catching speeders alone. Or we could spend 100% on busting marijuana users. Priority decisions have to be made.
