The guy was trained by the military at Fort Lewis, Washington. He was trained as a sniper. He became an assasin, terrorist nutcase. I suppose it's possible he was acting alone... I'll put my guess on the "subtile" encouragement scenario... like... they had something on him so, he had nothing to lose... This particular media event stinks to high heaven... The constant unprovoked denials by the media, durring the murdurer's spree, that his deadly accuracy was "probably not the work of a trained military personel", bangs around my head a bit. Yuck!
