"We may never know why this happened."
That's the usual reaction when another "senseless" shooting leaves its trail of death and heartbreak. Not this time.
The vengeful gunman in last week's horrific rampage near Santa Barbara, California left a hate-filled, 141-page manifesto to explain it. Three were stabbed to death, three sorority girls shot to death, 13 injured. It was one student's self-described "day of retribution."
"My Twisted World" is, in part, a journal of growing romantic and sexual frustration. Girls went for other guys but not for him. Others were having sex while he was an unintentional virgin. Frustration morphed into loneliness, then desperation, then a hellish personal agenda of destroying what had hurt him.
