Actually under the "son of sam" laws, the victims would be notified, and given the opportunity to be a plaintiff.
the new law required that victims or their families be notified anytime a convicted person earned more than $10,000 from any source. Then the victims or families could sue to get some of the money.
Deutche bank and others failed to enjoin the case, but are still free to sue Trump separately, but there are limits to the time they have to do so, which may have already expired.
So in this case, the money goes to the state, for the general benefit of the people.
