Wouldn’t that be a federal crime, with BATF/FBI involvement?
Yeah, he's dust.
Ten years at least for this, then whatever he gets for committing firearm felonies on parole for whatever crime he did to become a felon in the first place.
BATFE is struggling for relevance these days and may even try to 'top' the FBI by seeking to hit him with domestic terror charges or some other kind of sentence multiplier.
He won't be talking his way out of this mess. That's for sure.
