The news is now saying that he had targeted Giffords because she "dissed him" at a prior public appearance. He asked a question that was out of left field and she answered it the best she could. He, evidently, was not satisfied with the answer and thought he was slighted in some way. I have been hearing other peoples accounts of contacts with the suspect in the past and he sounds like he is bat ******* crazy. It is a shame that his parents did not recognize that he was in need of psychiatric care, but they may not be that stable themselves.
