No. Typically a 72 hour mental health evaluation and civil commitment hearing are necessary to medicate someone involuntarily. He would not be given psychotropics for the sake of appearance by any responsible health professional. It would be necessary only if he was a danger to himself or others, which in this case is a statement of the obvious.

My guess is he was evaluated by mental health officials over the weekend prior to his arraignment on Monday, and it was deemed necessary to pacify him. Thorazine is a powerful, older, antipsychotic and rarely used because of its side effects, more likely he was sedated with haldol. Seeing the suspect in court he did exhibit some symptoms of psychotropics including heavy eyelids, dizziness (head bobbing), enlarged pupils, and shuffling (though that may be from the leg irons).
