Where are you getting the idea that 10 innocents are being deported for every 1 illegal? Or that the "majority" of people supporting the crackdown would support that?
The information I can find suggests only a handful of cases, maybe a dozen, out of 600,000 or so.
I'm saying that the majority of the people supporting the crackdown don't care about the fact that the crackdown may break the law. Which is demonstrated by the fact that these people totally don't care of what is the number of innocents deported. You can see these people saying "we should deport the illegals", but how often you can see them saying "but I also want to know the number of innocent deported, and if this number is too high, we should stop the deportation"?
I'm not saying what is happening right now is 10 vs 1, and I did not in my comment. These numbers were illustrative, to explain that if you want to "apply the law", you should care about how many illegals are not deported AND how many innocents are deported.
This is the demonstration that people supporting the crackdown don't do it because they want to see the laws being applied, they just want "the laws that benefit them" to be applied. So we should stop pretending these people are acting because of their love for justice or for the laws.
edit: another way of explaining what I want to say: if you care about "applying the law", then you know that the correct measure will be a balance between the false positive and false negative. The large majority of the discourse of people supporting the crackdown is denying that. They are saying that "every single illegal must be deported". This discourse is explicitly saying that not deporting 1 single illegal is still not fine, and does not mention anywhere the balance with false positive. It shows that they don't care about "applying the law".
(And about "an handful of cases", that would be extremely unrealistic. Maybe you are talking about the number of cases that are surfaced, which is only a small proportion of the real numbers of case, as it is for all false positive)
