CRAFT and Decision-making: A Listener Weighs In

Dominique tells the story of a dad who sees his son's truck at a saloon. Not wanting the son to drive home intoxicated, dad uses an extra key to drive the truck home, parking it a block away. The son returns home intoxicated, ranting about his "stolen truck."  Dad stays silent while the son calls the police. They arrive and the intoxicated son rages. Dad tells police (but not the son) where the truck is. A listener says this whole scenario about dad parking truck away seems passive-aggressive, and asks what purpose was served. Was an enraged son the ultimate goal, so the police would arrest him?  Why did the father take no steps to alleviate his son's anxiety and anger? Wouldn't the CRAFT method say that when the son came home, he should see the truck in the driveway and get a brief explanation from dad on why it was there? Wouldn't the next day, when the son was sober and both parties more calm, be the time to discuss?
