Look, I may be wrong, OK? I honestly don't know. I wasn't trying to hurt anyone by suggesting the possibility. The shooter may have had 20 different things wrong with his mind and what happened with Rob's banning may have been only a small factor.
Trying to read the mind of a deranged murderer is almost impossible to do when he left few written clues behind, and all possibilities need to be looked at.
This has been a miserable experience for me just bringing up the possibility.
