You mean AIM? I don't think this was some organizational thing.
Even most terrorists/revolutionaries/anarchists wouldn't approve of this sick murder.
Whoever did this is mainly a sick person--a psychopath--who is influenced by AIM propaganda in my opinion.
AIM propaganda provides a kind of self-justification, a rationalization for his deviance.
HE needs to see himself as a revolutionary instead of a child-rapist and killer.
Ok now that has more credence.
