the ice cream lady didn't like him. this is an ongoing pervasive problem. something should have been done long before we got to this point, and that's not to point a finger and say somebody else is to blame, but it should have been addressed. if he presented these issues when he was a young child and this has always been a problem, and think it was dr. jeff at the top of our show talking about he's brooding, he's depressed, you know, he's exhibiting these particular personality traits, why was there no institutionalization when he was younger, you know. we talked about he was on meds. what was the diagnosis? there's so much unknown right now. but it's disturbing to me that we could have gotten this far along and i think brian nailed it when he said, when did they know and what did they know? that and my answer, how do we prevent this in the future? >> my guess is we're ig probably going to learn about the medications he was on, the treatment he received.
