The social work expert seems unbiased, IMO. He just reports what he has examined -- he remarks that the case-workers had too many cases -- as we have heard so often -- and he says that things were not followed-up as well as they should have been. So things were very tuff for TS and his 3 brothers. When Aaron (Smith) McGruder testified, I saw such a huge difference in the two brothers. A pity, really, but Aaron shows something we all know -- that someone who really tries to stay on the right course can succeed if his willpower is strong enuff.
