If someone argues: "cats are bad at rodent control because they spend very little time each day catching mice" that might be missing the point. But a better analogy might be "cats are bad at rodent control because they spend very little time each day catching mice, and I keep seeing mice-droppings everywhere". Pulling away from the analogy, the argument seems to be "There is a lot of hints that high-level crime still persists, and yet cops aren't spending much time fixing it, so their job must not be fighting high-level crime".
