Incidentally, 'proper ID' also consists of two individuals who will swear that they have personal knowledge of who you are, and that you are indeed who you say you are.
Also, did you know that Public Notary's (Government-approved-document-and-'ID'-generators) are required to perform their duties for individuals without any other form of 'ID' other than their personal knowledge of them? Makes you kind of wonder about that little discrepancy in the Mandatory-ID-Is-Splendid chest thumper's rhetoric -for those of you that can still think for yourselves. Makes Me glad Claire Wolfe is no longer lurking or posting here.
Just think - prior to 1967 there was NO Federal law regulating the sale of guns. Makes me wonder how we survived.
