They would not need a database to tally up the raw number of permits by state. That information is probably available by making a simple phone call to whatever agency in each state issues the permits. In my home state, state statute forbids releasing the names of permit holders. However, the state police can and will tell anyone who calls how many permits have been issued. I obtained the number for my town just last week, to use as a talking point in addressing the town council about changing a local law. I didn't even have to submit an FOI request. Just made a phone call.
So ... if they actually considered compiling a database, there had to be some projected use for the information to be contained therein. Either they WERE going to publish it (in some form or other, printed or on-line) ... or they were going to sell it. My guess still leans toward sell. It's common knowledge that printed newspapers are struggling to retain relevancy in the on-line age, and they are looking for ways to replace income lost due to declining subscriptions and shrinking advertising revenue. Collecting data in the name of "journalism" and then selling said data would seem a natural (if perhaps ethically questionable) tactic.
