This is pathetic news .  These people have become the bad guys.   As Kirk Douglas the actor said years ago when complimented on his kids and not taking credit for it " you can be a great parent and your kids turn out bad---you can be a bad parent and they turn out good " .     I can understand parents of young kids having to pay for repairs if they burn a school playground---but this ?   To sue the killers parents over this is shameful .  If these parents win--all parents are in deep trouble. The second our kids leave the home we can only hope they won't harm anyone. If we can lose everything for a mistake they make , we need to turn our kids over to the state.
