Another thing I've been looking at are large groups of cults committig mass murder/suicide, and I've been goig over what cult experts have to say every time such an incidet occures.
Toward the end of the year 2000, when crime boss David Miscaviage of the Scientology crime syndicate set the amusigly bizarre goal of trying to destroy the mental health idustry by the year 2000, I thought at the time that the criminal cult was ripe to be the next Jonestown.
One thing I noticed was that there _aren't_ good earmarks of a cult which one can point to and say, "that means there's a 40% chance the cult leaders will order a mass murder/suicide." There appear to be no outward indicators despite the fact that Jonestown _practiced_ committing sucide 42 times (the umber 42 probably being a coincidence, all you HHGTTG fans.)
Despite there being no classical earmarks of the likelyhood of mass murder/suicides, there does seem to be a set of requirements that cult followers adhear to before such incidents happen. Scientology holds most of these requirements except for one; a major one: followers are usually in the criminal cult for less than 2 years. There's a constant flow of financial swindles and victims of fraud among the 99% of the rubes that come in, empty their pockets, twigg to the fraud, and then move on, poor but much wiser.
Contrast that to cults which experience mass murder suicides. They have larger percentages of followers that have been in for decades with small percentages of short-term financial victims. Even with the horribly debilitative braiwashing that Scientology forces its victims to pay for, only a small percentage of their victims become so far gone as to fall into a mindset which would allow themselves to kill themselves or others on order.
So I wouldn't expect the Scientology cult to experience a mass murder/suicide. If its ringleaders were to be raided and indicted, I would expect their ringleaders to order their remaining followers to engage in massive racketeering, assault, arson and the like, but I wouldn't expect them to quietly go off to Griffith Park and eat chocolate pudding one last time.
