I think that if you paid for your home with criminal activity you should forfeit that to repay the victims of your crimes. If your legal and illegal stuff is together, tough shit.
At the very least, I believe the assets would be returned to them if it turns out they are found not guilty. So they are seized but not gone for good.
Civil forfeiture may be unjust, but it is definitely a product of, and tightly governed by, law.
It is also irrelevant to this case, in which criminal, not civil, forfeiture is sought.
