There's another of his friends/associates who was shown his "gun room".
One of the dealers said he was no novice.
Girlfriend was in the car while he was making a purchase. (She knows soooooo much more...but not about the event itself.)
The lead FBI invetigator - Aaron Rouse, just by happenstance, is married to John Podesta’s daughter.
Watch the pressers when the sheriff is talking. Rouse is staring at the sheriff so hard you can see the hole being burned into the back of his skull. The sheriff is always looking highly stressed.
Now we can play six degrees of Soros - Rouse, Podesta, Clinton, Soros.
Of course, this is pure connect-the-dots speculation. Your mileage may vary.
