Doubt the conventional wisdom unless you can verify it with reason and experiment.
It wouldn't matter whether you were Latino or Hispanic or Norwegian. If you didn't have proof of citizenship and if the police officer had reasonable suspicion, he would ask and verify your citizenship. I mean, that's the way that it is. That's what the federal law says. And that's what the law in Arizona says.
Trust, but verify.
Aristotle maintained that women have fewer teeth than men; although he was twice married, it never occurred to him to verify this statement by examining his wives' mouths.
In properly organized groups no faith is required; what is required is simply a little trust and even that only for a little while, for the sooner a man begins to verify all he hears the better it is for him.
