You&#x27;re missing the point.  &quot;Too attenuated&quot; presumably does have case law, as do things like &quot;substantially related to a compelling government interest&quot; or &quot;probable cause&quot;.  Those have magnificent, overflowing volumes of decisions enumerating whether they apply to particular circumstances.  And yet, oddly enough, it works better to reason backwards from the desired conclusion in a particular case to the most convincing reasoning that could support it, than the reverse.
