That still seems reasonable to me, though. If there’s evidence that they knew what they were doing, put it to a trial to determine culpability. If they’re not obviously in a position to have known better, I can see not prosecuting them, but prosecution is the normal next step when someone seemingly knowingly commits a crime. If it turns out that they really all got scammed, they’ll be found innocent.
I’m also not sure how it will proceed, but I think it’s much more fucked up if a non-party to a criminal case has assets seized. Given that there are currently sanctions against Russia, I could see it being seized separately by the DOJ and/or IRS, but I’d honestly much prefer that it go through a trial instead of just having the DOJ decide. At least then they can have a jury if they want and they can defend themselves. Civil forfeiture is fucked up
