Interesting insight into the suspect.
Two things of note: When they did the survey with the assassins (i.e. Chapman, Sirhan Sirhan) there was some major life catalyst before the shooting (as they indicated, JL being kicked out of school) and practicing with a weapon shortly before the incident was a strong indicator (as JL did)...I wonder how many cases we will have to keep saying "All the signs were there" about before we finally figure out a way to be proactive.
