Rumors are circulating that the whole agency might go under the bus between now and Votin' Season if this turns out to be a big enough millstone around the administration's neck. Seeing as how the BATFE is basically a taxpayer-funded GOP Vote-Generating Machine and has been for more than twenty years now, I am less skeptical about this than I would be otherwise.
While I wouldn't hold my breath expecting common sense from the federal government, if they were at all serious about reform, they'd roll the firearms industry regulation and tax-collecting functions back into Treasury, and ditch the redundant field agents.
Having a dedicated Agency responsible for "gun crimes" creates an incentive to find and, if necessary, manufacture gun crimes in order to justify their existence.
Sure, the FCC and FAA and USDA are no fun to deal with, but they rarely burn down churches full of people or smuggle machine guns to Mexican dope gangs.
