Well ... yeah. Of course he did. But then, that could be said of anyone harvesting navel oranges, or sewing hems on slacks. Preparing items for future use is what we do. ATF is stating this as if it's a criminal act to have done ... the keeping for future use part, I mean.According to a complaint filed earlier this month, Struve "planned to use the items at some uncertain date in the future."
We'll probably hear more as the investigation finds more.
As for whether he's fringe with a few marbles lost, consider that ~50 guns isn't too much different than many folks. In 1985, someone with 50 guns and numerous full-autos wouldn't have been deemed short of a sixpack, yet today he is. Granted, the true military-grade items (grenades, launchers, C4) seem a bit over the top.
The mere fact he was stocking up is little different than many here, even with full-autos as part of the collection. No facts yet, but it's entirely possible that he acquired much or all of it surreptitiously. That's verboten, sure, 'cause the gubmint has a law. And with the C4 and launchers, it begs the question about the goal of his preparations. But, other than the likely surreptitious acquisitions, with no violent actions yet, what's the infraction?
