Don't stores in Manhattan employ security guards? Most busy central London shops certainly do, at least at busy times of day. That seems to sufficiently deter shrinkage, without having to resort to lock boxes on the shelves. Sometimes you'll see high-value items (like expensive bottles of alcohol) with security tags that need to be removed at checkout, but I don't recall seeing locked down shelves.
