Both of the Russians – Maria Butina and Alexander Torshin – have, by the way, long well documented histories as advocates for gun ownership and were founders of Right to Bear Arms, which is not an intelligence front organization of some kind and is rather a genuine lobbying group with an active membership and agenda. Contrary to what has been reported in the mainstream media, Russians can own guns but the licensing and registration procedures are long and complicated, which Right to Bear Arms, modeling itself on the NRA, is seeking to change.
Maria Butina, a graduate student at American University, is now in solitary confinement in a federal prison, having been charged with collusion with Torshin and failure to register as an agent of the Russian Federation. It is unusual to arrest and confine someone who has failed to register under the Foreign Agents Registration Act of 1938, but she has not been granted bail because, as a Russian citizen, she is considered to be a "flight risk," likely to try to flee the US and return home. It is to be presumed that she is being pressured to identify others involved in her alleged scheme to overthrow American democracy through NRA membership.
Indeed, in any event, it would be difficult to imagine why anyone would consider the NRA to be a legitimate intelligence target. It only flexes its admitted powerful legislative muscles over issues relating to gun ownership, not regarding policy on Russia. In short, Butina and by extension Torshin appear to have done nothing wrong. Both are energetic advocates for their country and guns rights, which they appear to believe in, and Butina's aggressive networking has broken no law except not registering, which in itself assumes that she is a Russian government agent, something that has not been demonstrated. To put the shoe on the other foot, will every American who now travels to Russia and engages in political conversations with local people be suspected of acting as an agent of the US government? Once you open the door, it swings both ways.
One might dismiss the entire Affair Butina as little more than a reflection of the anti-Russia hysteria that has been sweeping the United States since Hillary Clinton lost the 2016 election, but that would be unfair to those remaining honest FBI agents who may have investigated Butina and Torshin and come up with what they believed to be a plausible case for an indictment. There were possibly suspicious money transfers as well as email intercepts that might be interpreted as incriminating.
But two important elements are clearly missing. The first is motive. Did the Kremlin seriously believe that it could get anything substantial out of having a gun totin' attractive young Russian woman as a life member in the NRA? What did the presumed puppet masters in Moscow expect to obtain apart from the sorts of group photos including Butina that one gets while posing with politicians at the annual NRA convention? Sure, the photo might even evolve into a cup of coffee together, but what is the end game?
