I think the point is whether it's a good allocation of resources. Lets say you have two borders. One has a cursory check of documentation, so allows people to sail through. This costs 2X to man. Another has a more interactive exchange, but each interaction takes longer, so costs 5X to man. So you either pay 5X, or 2X and then have 3X to do something else with. Could you use that 3X to better protect the border through pro-active investigation and analysis?
