One would think, but that would be expensive in terms of time and resources as it would require a massive increase in (trained) manpower and other "overhead" resources (land and air transportation, food, overnight and temporary lodging, lawyers, medical services, etc., etc., etc.) to see deportations through to completion because, as we've seen, illegals, Democrats, woke leftists, bleeding-heart liberals et al find MANY ways to impede lawful deportation actions.

THIS tactic, on the other hand, "should" prompt more illegals to self-deport (at less cost and effort to the US raxpayer).

Why?

We tried "the carrot" (allowing illegals to choose when to go, to take some/most/all of their possessions/assets and giving them $2k-$3k plus a free airplane ticket if desired).

That worked for some, but those who didn't take "the carrot" now get "the stick" (take their possessions/assets and leave asap to avoid paying [retroactive] fines that may have already eaten up the value of most of their possessions/assets, but if they stay and are prosecuted for non-payment, they get forced deportation which means they take none of their possessions/assets with them plus they can't return to the US for any reason).

The smart ones "should" "see the writing on the wall" and voluntarily leave asap. There will, undoubtedly, be Democrat/leftist/liberal outcries and actions against this and those who (to the disservice of the illegals) convince illegals to "stay and fight", but their chances of success are dwindling as the screws keep tightening on the illegal alien problem.
