Seems about 100 times more likely that if something in this case is smoke and mirrors, it's the white trucks, not the tarot card.
The chance the card was a hoax was always slim in the first place, and that the card had a message about not revealing it to the media I think that reduces the hoax chance to about zero.
And it's still unclear whether there was a white truck with two men in it at the Manassas scene or whether that was just carryover from the (single witness) sighting in Montgomery County. NO ONE has seen ANYONE shooting from a truck.
As I pointed out in the "big" thread, there's ALWAYS going to be a white truck, SUV, or van at EVERY one of these shootings when they're near a busy intersection.
