Agree the likelihood of collecting even $50,000 is remote, but making the parent...likely single... might at least point at their letting their kids grow up feral. I am pleased these young thugs were tried as adults and given hard time. Even the accomplices got 20 hard years and not some cushy plea bargain that would have them shortly back on the streets.
However the parents will have to obtain legal council.....which will cost them. Not to mention their time and headaches wondering how it will turn out once all is said and done.
