No. He left a note. It’s not clear that he was a lunatic either.
He set fire to his house, with his wife and step-daughter, still inside. I don’t know about you, but that action alone, kind of SCREAMS lunatic, to me. Also, purposely piloting an airplane into a structure is, by definition, not a sane act. Regardless of his perceived(HIS perception, not yours)motive, the fact is that he tried to kill civilians that were complete strangers to him. That is attempted murder, no matter how you slice it.
Do not give the lefties any extra, unearned ammunition against the Tea Parties, or any other conservatives, for that matter, by trying to justify any portion of Mr. Stack’s motives or actions.
