Got it backward's my friend. *Because* I had been made aware of the phenomena of "Psychotic Break" linked to marijuana, I *THEN* decided to see if any corroborating evidence might be available in the form of known violent murderers.
It was. Of course this doesn't prove linkage, but it just adds to the pile of data. I also make a habit of pointing this out, not to prove anything to the dopers, but just to *IRRITATE* them. Did you find it irritating? If so, then it accomplished the purpose for which it was intended.
Please try to stick to arguments which don't violate Logic!
Please try to apply logic better.
You failed - it makes me laugh.
