According to the St. Louis Gun Rights Examiner, BATFE is now interesting in a new reporting requirement if you buy multiple long guns in a 5 day period. While this should require an act of Congress (and might run afoul of the Heller decision to boot), the Obama-led BATFE thinks they "may" be able to do it without all that messy process getting in the way.
We were warned before November's repudiation of Obama & Co. at the polls that they would simply move their focus from legislation to regulation. This and actions such as the Gulf oil drilling ban show the prognosticators were correct. We need to get the word on this out to the rest of the gun culture and put a quick halt to this one.
