Not his fault. He probably had some "mental" issues like the guy in Seattle.
Just after 9/11 we had an Arab Muslim who was the cousin of the one who owned a local gas station. He seriously desecrated a Catholic Church in Culver City, and thre Islamic tracts around the Altar. the cousin in the gas station knew nothing of course, except that his cousin was "mentally ill". He was caught two days later, and the iman at the King Fahd Mosque(Wahabite funded) in LA made the claim, along with his minions that he was "disturbed.
A Freeper in Philly recounted a similar story regarding another jihadist who also happened to be "mentally ill". I doubt coincidence..
The guy in Seattle was a terrorist. He killed Jewish women-age old ROP tradition kill women especially Jewish ones.
