We all know that ignorance of the law is no defence. So it

passing familiarity with it.
Given that this country's been passing laws for 900+ years
does anyone have a view on how long it would take to actually
read them all?
As an easier option, how far back to most of the laws that
people generally get into trouble with, go? I'd guess maybe 20-30
years. So as a "lightweight" option, how many laws would
we be talking about - and how long to skim through that lot?

I remember David Penhaligon saying in the 1980s that while queuing in the
Division Lobby once, he noticed that all the statutes were in bound volumes
along its length. And also that those from 1980 to 1985 took up as much
shelf space as those from 1066 to 1979.
So, all in all, a Sisyphean task.
