Murray can earn whatever he wants--there's no restriction
because the Jacksons waved "restitution" during the criminal trial to the shock of David Walgren & the DA's office. Had Judge Pastor issed a Restitution Order and Fine, all of Murray's earnings would go to pay that debt. But, there is the "Son of Sam" Law that could be applied:
A
Son of Sam Law is any
American law designed to keep criminals from profiting from the publicity of their crimes, often by selling their stories to
publishers. However, this is not in the same manner of
asset forfeiture, which is intended to seize assets acquired directly as a result of criminal activity. Where asset forfeiture looks to remove the profitability of crimes by taking away money and assets gained from the crime, Son of Sam laws are designed so that criminals are unable to take advantage of the notoriety of their crimes. Such laws often authorize the state to seize money earned from deals such as book/movie biographies and paid interviews and use it to compensate the criminal's victims. The term "Son of Sam" refers to the nickname of serial killer
David Berkowitz, the subject of a notorious 1978 murder case.
In certain cases a Son of Sam law can be extended beyond the criminals themselves to include friends, neighbors, and family members of the lawbreaker who seek to profit by telling publishers and filmmakers of their relation to the criminal. In other cases, a person may not financially benefit from the sale of a story or any other mementos pertaining to the crime—if the criminal was convicted after the date lawmakers passed the law in the states where the crime was committed.
