What is confusing? Government screw-ups are not justification for abandoning government action. This used to be a pretty standard policy of the left, considering how many of their programs were grossly mismanaged and abused. None of our laws were written for the situation we are in now. It was never a consideration that tens of millions of people who have no right to be in this country would nevertheless be here. The protections afforded to American citizens, and others legally present within our borders, cannot be extended to every person on the planet. It is not hard to prove citizenship. Neither for the government nor the accused party. That there are a few dozen cases out of literally millions is evidence that this is not a real problem, any more than a few aircraft mishaps out of millions of yearly flights are indicative of a widespread aviation safety threat. The recharacterization of deportation as some sort of punitive action similar to incarceration is the exact trick being used to slow down the process for the ultimate goal of preventing deportation entirely. Same with the refusal of an asylum claim. If you get on a plane to America without a Visa or passport, you are not allowed to leave the airport until you can be seen in front of a judge. You are put on the next flight back to your country. We have the ability for the vast, vast majority of illegal immigrants to quickly confirm their illegal status and return them to their country of origin. Since the problem has been allowed to grow to the tens of millions, there will unsurprisingly be some mistakes along the way. If those mistakes are measured in a fraction of a fraction of a percent, I don't have any problem with that. Once again, show me the American citizens being deported or denied entry back into the country by an intentional process and we will have some sort of agreement. But you can't show that. If you believe the people here illegally have a right to the resources of our country, we just have a fundamental disagreement. I do not believe they have any claim to medical treatment, education, assistance programs, or voting rights. Along those same lines, I do not believe they have any claim to our judicial system, unless of course we are attempting to incarcerate, fine, or otherwise restrict that human being from anything other than their unlawful presence within our borders. Once again, it is simply intentionally naive or disingenuous to act as though we can't figure out who the vast majority of the illegal aliens are. They didn't come here from Mars. They are overwhelmingly from countries south of our border that have fully functioning governments with records systems that track their citizens just as we track ours. The left is just trying to make this about something it isn't because ultimately what they want is for them to stay.
