I am uninvolved (thankfully, not many people have been confused) but on the topic of the meditation practice: years ago when reading the zizian.info writeup, I found the unihemispheric sleep part to be the most alarming & interesting part.
There are many strange altered states of consciousness found by experimentation, and I can totally believe that some form of auto-hypnosis + sleep deprivation - which would parallel many well-attested mind-altering practices in many different cultures & religions - could have bizarre effects or induce psychosis and hallucinating demonic entities, and turn an activist vegan into a murderer. (Their specific interpretation of 'unihemispheric' sleep may or may not be true. I would say that it's worth checking... except I'm not sure how one could either prudently or ethically investigate it, given the apparent consequences.)
And it would answer the question many people have been asking about how these unlikely-seeming murderers were made, in a way that the rest of it all does not.
