1. Oswald was given a job in what would eventually become the sniper's nest well in advance of the assassination. In effect, the target was brought to him, rather than seeking out the target.

2. The motorcade route was deliberately changed from going directly toward the freeway, to making a sharp right turn, slowing down to less than 10 mph, then another sharp left turn in front of the Book Depository, all against Secret Service regs.

3. No Secret Service on rooftops, or rear bumper of limo!
