I agree with Laurie...it sounds like he's just feeling sorry for himself again. He knew when he did the first line of coke, he was doing wrong, and he did it any way. He was given the PRIVILEGE of work release and he chose to do coke and get sent back.
The only thing I differ with on Laurie's advice, is selling the car and giving your parents the money, and only because your son has been able to manipulate THEM so well and would try to do so again, to get the money.
In my opinion, I would NOT do anything to help him pay this lawyer another $800. Your son is right where he needs to be, and he has a long way to go before he sees his own actions caused all this. He keeps focusing on the steaks, but he's totally missing the big picture of all the other stuff he has done.
I'm sorry you're going through this, but I'd let HP handle this one and keep out of it, if it were me.
Hugs and prayers!
