1. "(CNN)Mark Barnett had what he thought was a great get rich-quick scheme involving homemade bombs,

Target superstores, and well-timed trades on the stock market."
A registered sex offender, Barnett had previously been convicted of multiple felony offenses, including kidnapping, sexual battery with a weapon or force, and grand theft, according to the criminal complaint. He wears a GPS ankle monitor as part of his probation.
He wasn't going to short the stock, he was going to buy low and hold. He gave the bombs to someone else who was actually a probation officer!
Not quite the same motivation as McDowell. Had he been an immigrant, though.....
