WOW it's broken thinking like this that has blurred the line of our Constitution that liberals have twisted to the current rule of law. Illegals should have No legal standing under the Constitution and they DEFINATLY don't get ANY under the 14th Amendment. Period (this is just my opinion though....:))
Don't shoot the messenger: it's been that way since the US Supreme Court decided that way, back in 1898.
Now look at what you're really saying ... put yourself in a different country -- let's say England, just to keep things somewhat familiar -- and assume that a cop decides to look askance at you.
As you know, an English citizen enjoys certain protections from the excesses of government, especially including its law enforcement arm. I'm sure that you, a non-citizen, would be all in favor of those protections being extended to you as well, once you were placed into their legal system.
If you were to make an argument that you deserved such rights, I think you -- like most of us -- would start out by stating the principle that a person has certain inherent and unalienable rights, and that any valid system of law is bound to recognize them. That would include things like the right to due process of law. A person doesn't lose those unalienable rights simply because he crossed the border illegally, and we should not suppose that we can abrogate them.
I really don't like the idea that those unalienable rights can abrogated "because that person is illegal." It's too easy, once you do that, to think up other "becauses."
But again, the whole idea of making "being here" a felony, would simply swamp the legal system, to no good end. We can already deport illegals, and it's already a felony to come back once you've been deported.
