@georgetakei every classifier necessarily has false positives and false negatives. All other things being equal, if you increase one you decrease the other.

Even if you accept their lie that they only want to deport "criminals," implicitly that means they want to deport more "innocent" people. This tends to also be non linear. You will deport exponentially more "innocent" people for each additional "criminal."

Personally, I think it's worth questioning the premise of borders and classes of people who can be explicitly denied rights but I guess that's just because I'm an anarchist.
