ICE's current mission isn't to deport illegal immigrants. Its current mission is to antagonize anyone who is not a WASP, and seemingly these days, anybody who stands up for non-WASP citizens in the US. As can be easily ascertained by the sheer number of encounters where the officers insist that they don't actually care to see any papers proving the people they're arresting are legal US citizens (let alone legal US residents).

So your questions don't matter because you're arguing about a reality that doesn't exist.
