I don't know that is advanced. Criminals or those accused of being criminals have the option of doing things with their property until they are convicted unless they are seized beforehand. This means that someone running the domain names would be able to sell them off, duplicate them, make other arrangements etc until they are convicted. If they are seized beforehand, they are unable to do this. And note this is NOT the same as "guilty until proven innocent".
The current biker battle in Texas is a great example. The government has seized all of the 180-odd bikes belonging to the bikers arrested after the battle in Waco this weekend. Those bikes will be held, but as soon as the people are convicted, they will be forefiet and sold off.
If the government had NOT seized them and left them to stay there, you'd have other bikers coming in, hauling those bikes off, and either keeping them until their owners were released or convicted, or being sold off immediately. If their owner was convicted, what you most definitely would NOT see would be the government being able to get any of those bikes back so that they could make sure the owner forfeited them.
