dr. breggin testified that david had been taking anti-depressants on and off for years, and that, what david did, was the drugs' fault. so i think the whole thing evolves out of a progressive hammering of his brain by the drugs. >> it was drug-induced violence, the doctor told the jury. drug-induced murder. back in the courtroom, angie listened to this, and "upset" would not be quite the right word. >> it was laughable almost, and just that you can -- how much money they had to spend to find this guy who is going to say exactly what the defense wants him to say. >> were you afraid the jury would buy it? >> um, of course, you're always a little afraid. because it's scary to think that he could potentially get off with the insanity plea.
