Yes, thanks for the insight. The point I'm sneaking up on, is whether
it's "reasonable" for the average person to have an awareness, or
knowledge
of all the laws that they could fall foul of (or commit, depending on
if it's possible to break the law by accident). Given the volume of
material
involved. Just as relevant, can or should a constable have this knowledge.

I think the gist is that law is based on the "reasonable man" principle.
Most people should know if their actions, or intended actions, are against
the law. Esp for the vast majority of crimes.
