A letter-writer in Monday’s Letters section of The Wall Street Journal was rightly concerned about red tape redundancy, but he missed the mark on one form of it.

One can’t work with children without undergoing specific training and, in many states, extensive background checks. There’s value in those measures, but how about some coordination?
While living in New Jersey, I was fingerprinted for my teaching license in Somerset County and, later, in Middlesex County, despite having permanent certification in New York. I was then fingerprinted for gun purchases, coaching recreational soccer, and teaching Sunday school. At some point, it all becomes too exhausting.

There’s nothing redundant about being checked via immutable personal characteristics at each of those application points. Fingerprinting is an important way of determining that the person doing the applying is who he claims to be. Those multiple applications may or may not be by the same person.

Having been IDed by fingerprints and confirmed to be the same person across those multiple applications, though, there should be no need to repeat the rest of the applications beyond what’s unique to the function being applied for. Those repeats are what would be redundant and want better coordination.
