There's no due process anymore. Why do you believe you'll ever be granted a lawyer, let alone a phone call, or a court date? They're just out there assaulting and disappearing people.

You also get a court-appointed lawyer if you don’t have other options and staying silent in jail for a week is preferable to admitting whatever they want you to admit to secure a conviction.

Don’t Talk Without A Lawyer (Working for You) Present.™

I wish you well but you may be underestimating how far down we've gone. If you try to walk away or put up a fight, and you will be swarmed by cops who will take you to the ground with no concern for the injury they are doing. At the least you will be bleeding, at the worst you'll get some broken ribs or worse.

Once they're done beating on you, you will be detained, I won't say arrested, and you will be taken to an ICE facility where you will not get a phone call or access to a lawyer or medical care. After a day or two, maybe less, you will be transferred to an ICE facility a few states away, or maybe on the other side of the nation. Your friends and family will not be informed and will have no way to find you until ICE decides you've had enough and let's you go. Assuming they don't just deport you for the hell of it.

Remember, until you prove you're a citizen, you don't get due process. And of course, without due process you can't prove you are a citizen.

An app is supposed to override my goddamn birth certificate?

The issueance of said birth certificates is a power reserved to the states, and state-issued documents must be given full faith and credit. US citizenship is supposed to be secondary to someone's citizenship to the state. So, if the states have to give them credit, so too must the federal government.

Bold of you to assume they don’t already have your face and that they need to be in your vicinity to scan it.
