Rights are held by everyone, equally. Or they aren't "rights".
That said, I pretty strongly disagree with the principle AOC's backing, here. Canada's looking to seize Russian assets too (and just voted to recognize what's going on as a genocide), and I fully support that. The issue is not the seizure, it's the justification. The issue with civil asset forfeiture in the USA is that, in practical terms, there usually isn't any justification beyond the police being thieving shitheads.
Civil asset forfeiture should be limited to the assets of convicted felons. Not suspects, not charged-but-not-found-guilt defendants. Only those convicted. The law should be able to lock assets down until trial, but that's a separate concern.
And forfeitures like with Russian asset seizures shouldn't be under the same law in the first place, and should only apply to internationally-held properties, as punishment for egregious acts like genocide.
