I've been thinking that one way to keep smugglers and criminal aliens from being able to continue to commit crimes against our country as an alternative to holding them in our prisons would be to deport them from the continent and drop them somewhere where it would be extremely difficult for them to be able to come back to the US. This would be kind of inhumane in the case of marooning them on a remote area of the extreme southeastern region of Chile or Argentina or even dump them off in Antarctica or the Southern Falkland Islands. The other simple alternative would be the death penalty as well.
