Apparently you aren't reading anything that is not addressed directly to you but I've answered this before. The law that is currently on the books has been ignored for decades. At that point common law takes over. There is established precident for NOT enforcing the law. Therefore, when the lawyers and activists go to court for these illegals they site the fact that a law shouldn't be arbitrarily enforced, it's unfair to enforce it agaisnt their client since it has NOT been enforced against hundreds of thousands (now up to millions) of others.
A new law changes that.
