Either way, alone or not, this was not just Sudden Jihad Syndrome. It was planned, probably by a group, and instigated by an even larger group.
Thus ends the record of no successful terrorist attacks, other than SJS types, on US soil. Just a little over 4 months after the takeover by the Messiah.
A mope from Tennessee finds his way to Yemen carrying a Somali passport. A felon who is virtually unemployable has access to an SUV and THREE weapons, one an automatic rifle. OF COURSE this bozo is not acting alone. He almost certainly had never HEARD of Yemen until some jihadi took him under the Islamic wing. Crack and marijuana, maybe even a pistol or revolver, a thug like this would know how to obtain. A Somali passport and a passage to Yemen, not in a hundred years.
