The National Rifle Association has rallied gun-owners — and raised tens of millions of dollars — campaigning against the threat of a national database of firearms or their owners.

But in fact, the sort of vast, secret database the NRA often warns of already exists, despite having been assembled largely without the knowledge or consent of gun owners. It is housed in the Virginia offices of the NRA itself. The country’s largest privately held database of current, former, and prospective gun owners is one of the powerful lobby’s secret weapons, expanding its influence well beyond its estimated 3 million members and bolstering its political supremacy.

Others in the business of big political data, however, say the NRA is using similar tools to those employed by the campaigns of its nemesis, President Barack Obama.

While the organization took great umbrage in December when a newspaper published the names and addresses of gun owners in two New York counties, the group for years as been gathering similar information via the same public records as a matter of course.

In Virginia, for instance, a North Carolina-based firm called Preferred Communications filed an inquiry with the Virginia State Police in July 2009 asking “on behalf of the National Rifle Association” as to whether the names of concealed-carry permit holders could be purchased. The e-mail was obtained by BuzzFeed by Freedom of Information Act request.

“After people take a class, then you as an instructor, can send all their names to Washington and you get credit for that,” Weisser said. “If you can show you’ve taught enough classes, you can move up in the hierarchy as an NRA trainer.”

Moving up in the hierarchy can mean being licensed to teach more types of gun safety classes and being able to charge more, he said.

Obama wants you to believe that putting the federal government in the middle of every firearm transaction — except those between criminals — will somehow make us safer.

That means forcing law-abiding people to fork over excessive fees to exercise their rights. Forcing parents to fill out forms to leave a family heirloom to a loved one — standing in line and filling out a bunch of bureaucratic paperwork, just so a grandfather can give a grandson a Christmas gift. He wants to put every private, personal transaction under the thumb of the federal government, and he wants to keep all those names in a massive federal registry.

There are only two reasons for that federal list of gun owners — to tax them or take them.

That’s because section 103(i) of the Brady Act specifically bars federal agencies from retaining “any record or portion thereof generated by the [NICS] system,” and it prohibits the “registration of firearms, firearm owners, or firearm transactions” of those who pass the background check.

For this reason, the final rule was revised to conform to the legislative enactment setting a limit on how long the NICS may retain certain information on allowed transactions. The revised rule conformed to the 24-hour record retention provision in the Omnibus.
