Hypothetically, Trumps administration could be biased and target deportation of dark skinned Mexicans only while Obamas administration was competent and neutral in its enforcement for the law. This would lead to a case where the racist policy resulted in less deportations but a more humiliating and unfair treatment of deportees. Remember the goal is not to deport fewer people, but rather to be fair minded. A similar comparison can be made to racist cops who arrest black criminals. The issue isn't that they arrest criminals, but that they choose their targets by race alone.
