We have no idea he went to a medical confrence and said Muslims are justified attacking non believers.
We certainly don't know from other soliders that he tried to recruit during therapy sessions.
And of course we have no idea the fact that he had over 20 emails with an Al Queada recruiter.
And no idea from eye witnesses that he shouted Allahu Akbar while he murdered the soldiers.
But we do know we can throw out the "stress" excuse right? We have all the evidence of that! Oh wait, we don't.
Do you just want to pretend none of this exists? Is that your strategy?
