I think you're conceding too much here, Doug. There's no reason it shouldn't
be a case by case determination, but with a "case" arising only when a
boater is stopped for BWI, reckless behavior or other unlawful behavior.

so employing this logic, we don't need to license people to drive cars
either, and then only apply controls to each individual after they have
killed or maimed themselves and/or others or caused property damage?
