Impressive or not in a metrics oriented world putting a number on anything, no matter how feeble, is a significant advantage. Mix in all the hyperbole and scare-mongering about illegal immigrants, human traffickers and of course terrorists and you have a pretty unassailable position when justifying the program and expense. Alternative arguments on where the money would better spent are dead on arrival.
