Last week, Store B's AI caught the theft, logged it, and nobody moved — leaving the store that saw the crime more exposed than the one that stayed blind. In Part 2 of Detection's Dilemma, Don Carr and Jim Cords resolve the paradox by rebuilding Store B without changing a single piece of hardware. The fix isn't less detection — it's the half of the system the vendor doesn't sell you: a response doctrine. A defined recipient, a defined response, a logged outcome — three lines that convert timestamped liability into a documented legal defense. Detection sees; doctrine answers; you need both. Plus the version-one response doctrine you can write this afternoon. Loss. Liability. Law.
