Then there's the meds themselves...IF he's on meds, are they doing harm? I've seen people go through hell and be a lot worse because of the meds....including my brother.
He was on meds? I predicted this one. Oh, and “he wanted to talk to Hillary”... she’s so ... you know.
They always use the meds excuse in courts when either they want to cover up the truth and dismiss the witness, or when they want the witness to speak under their meds and influence and not under his or her own impressions of things.
I prefer a paranoiac witness than a one made “reasonable” by their meds.
