Droning on at the border

I have written more times than I can recall how high-tech border enforcement has never been as effective as people think/hope.  Many times, in fact, it is an abject and expensive failure.  No matter how overwhelming the evidence, lawmakers continue to push for virtual enforcement.  The latest example is using an unmanned drone in Texas.

This story revealed two things that I did not know.  First, Customs and Border Enforcement already has five such drones.  Second, drones have been patrolling the U.S.-Mexico border for a decade.

I don't have much to add.  It will be hyped.  It will be expensive.  It will do relatively little.
