If they were criminals, I would agree with you, but most of the *******, border jumper stowaway, H1B over-stayers, are only subject to civil fines, jail time, less than 11 Months, 29 Days, and getting kicked out of the country, none of which are criminal charges, according to Federal Statutes and both houses of Congress of the United States. But, going after actual criminals, who hide, evade, resist, etc is too time-consuming to generate the daily numbers, so that "concentrate on the criminals" thing, when right out the window, to generate the desired numbers.
