Just what is Demand Letter 3. Not sure yet..but here is another reference
here we go...how the ATF uses demand letters.
probably demand letter 3
Recently, ATF announced through the Federal Register our intent to initiate a new Demand Letter requiring the reporting of multiple sales of certain long guns by Federal Firearms Licensees, known as FFLs, in the four Southwest Border States. We took this step as a way to help gain actionable law enforcement intelligence which we believe will help reduce criminal firearms trafficking along the Southwest border.
Before we can actually issue the Demand Letter we must receive approval from the Office of Management and Budget for purposes of the paperwork reduction act. We expect to receive that approval in early January, 2011.
