I suppose so. Tell me, is it okay for the police to then steal that money? Perhaps the local sheriff should get the county to give him a right to steal the police money. And then the state attorney general should get the legislature to let him to steal that money. And then the U. S. attorney general should get Congress to allow him to steal that money.
Sorry, I don’t think anyone should have to prove ownership. Possession is 9/10ths of the law.
If no criminal act is proven, the money should remain with the person who had it.
You’d be surprised how many people say “It’s not mine. I didn’t know that was there” when they are caught with something they shouldn’t have.
If you are driving around in a car that isn’t your car, don’t be surprised if the 9/10’s rule doesn’t apply.
