I would love to see how those turn out. He's not actually taking the risk himself. They would still have to prove to the interviewing officer that all this isn't premeditated. How hard that is I don't know. I would love to know how those cases turn out. Are there similar cases like that on this forum with the final result?
He also throws out one liners like interviews in Florida are tough, Dallas is fair, San Fran is busy, etc. Wonder how accurate he is. Immigration is under Federal control, do different Federal offices really differ that much?
