Yoko was enraged by her husband's radial change in political orientation and there was a lot of real angry stress in their relationship in its final years. The question always has been did she in cahoots with some other ‘progressives’ in Hawaii arrange for the obsessed and crazed fan to be brought to NYC to eliminate Lennon before he started to divorce Yoko and pull his fortune away from ‘progressive causes’.
It’s only the-o-ry but I like it.
