How do I prove I’m not an illegal? Well “official” documentation of course. How do I prove that the “official” documentation isn’t forged? Well fingerprints of course? Retinal scans? Urine tests? But of course I have the right to refuse... if I don’t want to drive a car, or if I don’t want to work. Like it or not, that’s the path ahead I expect.
Yup. Now that they've managed to convince us that the common-law right to travel has an automobile exception, they can do just about anything they want to us.
