previously discussed how the gun-show loophole is an open invitation to criminals, particularly in the context of the the drug-cartel violence along the Mexico border, which is in fact being heavily fueled by guns purchased legally in the USA, many of them at gun shows.

As Chris Brown at Media Matters observes:

At gun shows buyers can purchase guns from private sellers without passing a background check. An investigation by the City of New York showed that even buyers that identified themselves as people who "probably couldn't pass a background check" were able to purchase guns at gun shows. The investigation also showed the wide variety of guns available at gun shows.

In addition, people on terrorist watch lists are not forbidden from purchasing guns and many have done just that. Gadahn's instructions come in the wake of Associated Press reporting that showed that more than 200 people with suspected terrorist ties bought guns legally in the United States last year. Following the AP report Representative Mike Quigley introduced an amendment to the Patriot Act that would give the Attorney General the authority to block gun sales to individuals on terror watch lists. The amendment was voted down.

Of course, the NRA remains adamantly opposed to closing the gun-show loophole. Indeed, they also remain opposed to bipartisan efforts to make it tougher for terrorists to buy guns.

One can only conclude that they are objectively pro-terrorist.
