> His point is that if your objective is to catch criminals, and in pursuit of that goal you're willing to set up checkpoints to collect fingerprints, and you're the US authorities primarily concerned with US criminals - wouldn't it be far better to set up those checkpoints inside the country?
The US has no laws against criminals travelling (assuming that they're not being pursued). It has laws against people with certain characteristics entering the country.
In short, the "catch criminals" premise was wrong.
