Unlike what happened with Chris Chan, Clint seemed to try to do everything right by Cobes when he was a minor. He put him in special ed, got him a therapist and got him on medication, made him keep up on hygiene, made him go to Job Corps, etc. But it never stuck, Cobes is honestly at a maximum mental age of 9 or 10 years old and nothing Clint could do would make him less dumb and less defiant. Yeah sure Clint could go through the legal steps to try to get Cobes committed to a group home, that's literally the only thing he could do to help him now as an adult, but I can see why he wouldn't want to. It will come down to that though, either a group home or rehab or jail. Cobes is too dumb to avoid them and it's a miracle he's still living on his own today.
