First post, hope I'm doing this right.
Regarding RS, I don't think he's purposely withholding information to save AS's butt, I'm sure he's told LE and they told him to keep the info to himself so it doesn't compromise the investigation. And maybe that's why TJ and TS aren't jumping down his throat. Also, I'm sure this whole ordeal isn't easy for him. He may have already lost a granddaughter, he may possibly be losing a daughter in a sense as well. Maybe that's part of the reason he is, or it seems like, he's trying to keep the finger from being pointed at AS. I'm not saying it's right, nor am I trying to defend him, I'm just trying to bring a new perspective to this. I'm not going to hate him for his actions, he may just be very conflicted in his feelings and that's why he seems to be back and forth in his statements and actions.
