I'm going to ask this question of our INGO armchair lawyers, but let me preface my question by stating my intent is not to pick on the gun shop for this. While visiting a very gun shop in Indianapolis today I saw several signs in the store that stated they would not except a state issued ID card as a valid form of ID for the purchase of a firearm. So my question is, does a valid state issued ID card not establish an individuals identity the same as a valid state issued drivers license? If I am not mistaken, both the drivers license and the ID card are issued by the BMV and require the same documents to establish your identity and residency before the card is issued. I am open to the possibility that it's the gun shops preference to only accept a drivers license, but I am just wondering.
