When you arrest them, where do you put them? It is a federal crime. Transport, there are an estimated 70+ thousand illegals in Wisconson alone. No through trains. 20 hour bus ride to TX. Arresting all of them in a short time, would mean feeding, and housing, a small problem. So arresting lets say 10 busloads a week, it would take maybe 2 years to get them all out. Thats ONE state.
